To make + the escaping clear and consistent, backslashes are also escaped. +* Updated `bitflags` dependency to 2.2.1. This changes the API of `CodegenConfig`. +* Prettyplease formatting is gated by an optional, enabled by default Cargo + feature when depending on `bindgen` as a library. +* Items are now parsed in the order they appear in source files. This may result in + auto-generated `_bindgen_*` names having a different index. +* Use default visibility for padding fields: Previously, padding fields were + always public. Now, they follow the default visibility for the type they are + in. +* Compute visibility of bitfield unit based on actual field visibility: A + bitfield unit field and its related functions now have their visibility + determined based on the most private between the default visibility and the + actual visibility of the bitfields within the unit. -## Deprecated +## Removed +* Remove redundant Cargo features, which were all implicit: + - bindgen-cli: `env_logger` and `log` removed in favor of `logging` + - bindgen (lib): + + `log` removed in favor of `logging` + + `which` removed in favor of `which-logging` + + `annotate-snippets` removed in favor of `experimental` + +* Prettyplease is available as a `Formatter` variant now. + +# 0.65.1 + +## Fixed + +* The `Builder::rustfmt_bindings` method was added back and tagged as + deprecated instead of being removed. +* Broken documentation links were fixed. + +# 0.65.0 + +## Added + * Added the `Builder::default_visibility` method and the + `--default-visibility` flag to set the default visibility of fields. (#2338) + * Added the `--formatter` CLI flag with the values `none`, `rustfmt` and + `prettyplease` to select which tool will be used to format the bindings. The + default value is `rustfmt`. (#2453) + * Added the `Builder::formatter` method and the `Formatter` type to select + which tool will be used to format the bindings. (#2453) + * Added the `Builder::emit_diagnostics` method and the `--emit-diagnostics` + flag to enable emission of diagnostic messages under the `experimental` + feature. (#2436) + * Added support for the `"efiapi"` calling convention (#2490). + * Added the `ParseCallbacks::read_env_var` method which runs everytime + `bindgen` reads and environment variable. (#2400) + * Added the `ParseCallbacks::generated_link_name_override` method which allow + overriding the link name of items. (#2425) + * Add support for C `enum`s when generating code while using the + `--wrap-static-fns` feature. (#2415) + +## Changed + * Static functions with no arguments use `void` as their single argument + instead of having no arguments when the `--wrap-static-fns` flag is used. + (#2443) + * The source file generated when the `--wrap-static-fns` flag is enabled now + contains `#include` directives with all the input headers and all the source + code added with the `header_contents` method. (#2447) + * The source file generated when the `--wrap-static-fns` flag no longer uses + `asm` labeling and the link name of static wrapper functions is allowed to + be mangled. (#2448) + * The documentation of the generated `type` aliases now matches the comments + of their `typedef` counterparts instead of using the comments of the aliased + types. (#2463) + * The `Builder::rustfmt_bindings` methods and the `--no-rustfmt-bindings` flag + are now deprecated in favor of the formatter API. (#2453) + +## Removed + * The following deprecated flags were removed: `--use-msvc-mangling`, + `--rustfmt-bindings` and `--size_t-is-usize`. (#2408) + * The `Bindings::emit_warnings` and `Bindings::warnings` methods were removed + in favor of `--emit-diagnostics`. (#2436) + * Bindgen no longer generates C string constants that cannot be represented as + byte slices. (#2487) + +# 0.64.0 + +## Added + * Added a new set of flags `--with-derive-custom`, + `--with-derive-custom-struct`, `--with-derive-custom-enum` and + `--with-derive-custom-enum` to add custom derives from the CLI. + * Added the `--experimental` flag on `bindgen-cli` and the `experimental` + feature on `bindgen` to gate experimental features whose implementation is + incomplete or are prone to change in a non-backwards compatible manner. + * Added a new set of flags and their equivalent builder methods + `--wrap-static-fns`, `--wrap-static-fns-suffix` and `--wrap-static-fns-path` + to generate C function wrappers for `static` or `static inline` functions. + This feature is experimental. + +## Changed + * Fixed name collisions when having a C `enum` and a `typedef` with the same + name. + * The `ParseCallbacks::generated_name_override` method now receives `ItemInfo<'_>` as + argument instead of a `&str`. + * Updated the `clang-sys` crate version to 1.4.0 to support clang 15. + * The return type is now omitted in signatures of functions returning `void`. + * Updated the `clap` dependency for `bindgen-cli` to 4. + * Rewrote the `bindgen-cli` argument parser which could introduce unexpected + behavior changes. + * The `ParseCallbacks::add_derives` method now receives `DeriveInfo<'_>` as + argument instead of a `&str`.

Rustified enum +/// +/// If none of the above patterns match, then bindgen will generate a set of Rust constants. +/// +/// # Clang arguments +/// +/// Extra arguments can be passed to with clang: +/// 1. [`clang_arg()`](#method.clang_arg): takes a single argument +/// 2. [`clang_args()`](#method.clang_args): takes an iterator of arguments +/// 3. `BINDGEN_EXTRA_CLANG_ARGS` environment variable: whitespace separate +/// environment variable of arguments +/// +/// Clang arguments specific to your crate should be added via the +/// `clang_arg()`/`clang_args()` methods. +/// +/// End-users of the crate may need to set the `BINDGEN_EXTRA_CLANG_ARGS` environment variable to +/// add additional arguments.

These regular expressions will be enclosed in parentheses and +/// anchored with `^` and `$`. So, if the argument passed is ``, the regular expression to be +/// stored will be `^()$`. +/// +/// As a consequence, regular expressions passed to `bindgen` will try to match the whole name of +/// an item instead of a section of it, which means that to match any items with the prefix +/// `prefix`, the `prefix.*` regular expression must be used. +/// +/// Certain methods, like [`Builder::allowlist_function`], use regular expressions over function +/// names.

This item can take one of the +/// following: +/// - A string literal with the flag if the type of the field implements the [`AsArgs`] trait. +/// - A closure with the signature `|field, args: &mut Vec| -> ()` that pushes arguments +/// into the `args` buffer based on the value of the field. This is used if the field does not +/// implement `AsArgs` or if the implementation of the trait is not logically correct for the +/// option and a custom behavior must be taken into account. +/// - The `ignore` literal, which does not emit any CLI arguments for this field.

That ties our hands when it comes to linking: ["Why isn't `bindgen` generat As far as generating opaque blobs of bytes with the correct size and alignment, `bindgen` can do pretty well.

Instead, use the `Default` trait. You can either enable this when +constructing the `Builder` using the [`derive_default`](https://docs.rs/bindgen/latest/bindgen/struct.Builder.html#method.derive_default) +method, or you can implement this per struct using: + +```rust,ignore +impl Default for SRC_DATA { + fn default() -> Self { + unsafe { std::mem::zeroed() } + } +} +``` + +This makes it possible to initialize `SRC_DATA` by: + +```rust,ignore +SRC_DATA { + field_a: "foo", + field_b: "bar", + ..Default::default() +} +``` + +In the case bindgen generates a padding field, then this field will +be automatically initialized by `..Default::default()`. + +### How to generate bindings for a custom target? + +To generate bindings for a custom target you only need to pass the [`--target`](https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-target) +argument to `libclang`.

In order to access that data, it provides +the `as_slice` unsafe method: +```rust,ignore + // SAFETY: there's at least `len` bytes allocated and initialized after `myrecord` + let payload = unsafe { myrecord.payload.as_slice(myrecord.len) }; +``` +There's also `as_mut_slice` which does the obvious. + +These are `unsafe` simply because it's up to you to provide the right length (in +elements of whatever type `payload` is) as there's no way for Rust or Bindgen to +know. In this example, the length is a very straightforward `len` field in the +structure, but it could be encoded in any number of ways within the structure, +or come from somewhere else entirely. + +One big caveat with this technique is that `std::mem::size_of` (or +`size_of_val`) will *only* include the size of the prefix structure. if you're +working out how much storage the whole structure is using, you'll need to add +the suffix yourself. + +## Using Dynamically Sized Types + +If you invoke bindgen with the `--flexarray-dst` option, it will generate +something not quite like this: + +```rust,ignore +#[repr(C)] +struct MyRecord { + pub timestamp: time_t, + pub seq: ::std::os::raw::c_uint, + pub len: usize, + pub payload: [::std::os::raw::c_char], +} +``` +Rust has a set of types which are almost exact analogs for these Flexible Array +Member types: the Dynamically Sized Type ("DST"). + +This looks almost identical to a normal Rust structure, except that you'll note +the type of the `payload` field is a raw slice `[...]` rather than the usual +reference to slice `&[...]`. + +That `payload: [c_char]` is telling Rust that it can't directly know the total +size of this structure - the `payload` field takes an amount of space that's +determined at runtime. This means you can't directly use values of this type, +only references: `&MyRecord`. + +In practice, this is very awkward. So instead, bindgen generates: +```rust,ignore +#[repr(C)] +struct MyRecord { + pub timestamp: time_t, + pub seq: ::std::os::raw::c_uint, + pub len: usize, + pub payload: FAM, +} +``` + +That is: +1. a type parameter `FAM` which represents the type of the `payload` field, +2. it's `?Sized` meaning it can be unsized (ie, a DST) +3. it has the default type of `[c_char; 0]` - that is a zero-sized array of characters + +This means that referencing plain `MyRecord` will be exactly like `MyRecord` +with `__IncompleteArrayField`: it is a fixed-sized structure which you can +manipulate like a normal Rust value. + +But how do you get to the DST part? + +Bindgen will also implement a set of helper methods for this: + +```rust,ignore +// Static sized variant +impl MyRecord<[::std::os::raw::c_char; 0]> { + pub unsafe fn flex_ref(&self, len: usize) -> &MyRecord<[::std::os::raw::c_char]> { ... } + pub unsafe fn flex_mut_ref(&mut self, len: usize) -> &mut MyRecord<[::std::os::raw::c_char]> { ... } + // And some raw pointer variants +} +``` +These will take a sized `MyRecord<[c_char; 0]>` and a length in elements, and +return a reference to a DST `MyRecord<[c_char]>` where the `payload` field is a +fully usable slice of `len` characters. + +The magic here is that the reference is a fat pointer, which not only encodes +the address, but also the dynamic size of the final field, just like a reference +to a slice is. This means that you get full bounds checked access to the +`payload` field like any other Rust slice. + +It also means that doing `mem::size_of_val(myrecord)` will return the *complete* +size of this structure, including the suffix. + +You can go the other way: +```rust,ignore +// Dynamic sized variant +impl MyRecord<[::std::os::raw::c_char]> { + pub fn fixed(&self) -> (&MyRecord<[::std::os::raw::c_char; 0]>, usize) { ... } + pub fn fixed_mut(&mut self) -> (&mut MyRecord<[::std::os::raw::c_char; 0]>, usize) { ... } + pub fn layout(len: usize) -> std::alloc::Layout { ... } +} +``` +which takes the DST variant of the structure and returns the sized variant, +along with the number of elements are after it.

The set of template parameters appearing in -//! the program is finite, as is the number of IR items. We start at our -//! lattice's bottom element: every item mapping to an empty set of template -//! parameters.

Fix-point analyses on the IR using the "monotone framework". +//! +//! A lattice is a set with a partial ordering between elements, where there is +//! a single least upper bound and a single greatest least bound for every +//! subset. We are dealing with finite lattices, which means that it has a +//! finite number of elements, and it follows that there exists a single top and +//! a single bottom member of the lattice. For example, the power set of a +//! finite set forms a finite lattice where partial ordering is defined by set +//! inclusion, that is `a <= b` if `a` is a subset of `b`.

A monotone function `f` is a function where if `x <= y`, then it holds that +//! `f(x) <= f(y)`.

Discover which template type parameters are actually used. +//! +//! ### Why do we care? +//! +//! C++ allows ignoring template parameters, while Rust does not. Usually we can +//! blindly stick a `PhantomData` inside a generic Rust struct to make up for +//! this. That doesn't work for templated type aliases, however: +//! +//! ```C++ +//! template +//! using Fml = int; +//! ``` +//! +//! If we generate the naive Rust code for this alias, we get: +//! +//! ```ignore +//! pub(crate) type Fml = ::std::os::raw::int; +//! ``` +//! +//! And this is rejected by `rustc` due to the unused type parameter. +//! +//! (Aside: in these simple cases, `libclang` will often just give us the +//! aliased type directly, and we will never even know we were dealing with +//! aliases, let alone templated aliases. It's the more convoluted scenarios +//! where we get to have some fun...) +//! +//! For such problematic template aliases, we could generate a tuple whose +//! second member is a `PhantomData`. Or, if we wanted to go the extra mile, +//! we could even generate some smarter wrapper that implements `Deref`, +//! `DerefMut`, `From`, `Into`, `AsRef`, and `AsMut` to the actually aliased +//! type. However, this is still lackluster: +//! +//! 1. Even with a billion conversion-trait implementations, using the generated +//! bindings is rather un-ergonomic. +//! 2. With either of these solutions, we need to keep track of which aliases +//! we've transformed like this in order to generate correct uses of the +//! wrapped type. +//! +//! Given that we have to properly track which template parameters ended up used +//! for (2), we might as well leverage that information to make ergonomic +//! bindings that don't contain any unused type parameters at all, and +//! completely avoid the pain of (1). +//! +//! ### How do we determine which template parameters are used? +//! +//! Determining which template parameters are actually used is a trickier +//! problem than it might seem at a glance. On the one hand, trivial uses are +//! easy to detect: +//! +//! ```C++ +//! template +//! class Foo { +//! T trivial_use_of_t; +//! }; +//! ``` +//! +//! It gets harder when determining if one template parameter is used depends on +//! determining if another template parameter is used. In this example, whether +//! `U` is used depends on whether `T` is used. +//! +//! ```C++ +//! template +//! class DoesntUseT { +//! int x; +//! }; +//! +//! template +//! class Fml { +//! DoesntUseT lololol; +//! }; +//! ``` +//! +//! We can express the set of used template parameters as a constraint solving +//! problem (where the set of template parameters used by a given IR item is the +//! union of its sub-item's used template parameters) and iterate to a +//! fixed-point. +//! +//! We use the `ir::analysis::MonotoneFramework` infrastructure for this +//! fix-point analysis, where our lattice is the mapping from each IR item to +//! the powerset of the template parameters that appear in the input C++ header, +//! our join function is set union. The set of template parameters appearing in +//! the program is finite, as is the number of IR items. We start at our +//! lattice's bottom element: every item mapping to an empty set of template +//! parameters. Our analysis only adds members to each item's set of used +//! template parameters, never removes them, so it is monotone. Because our +//! lattice is finite and our constraint function is monotone, iteration to a +//! fix-point will terminate. +//! +//!
