### Release Notes

<details>
<summary>rust-lang/rust-bindgen (bindgen)</summary>

###
[`v0.69.0`](https://togithub.com/rust-lang/rust-bindgen/blob/HEAD/CHANGELOG.md#0690-2023-11-01)

[Compare
Source](https://togithub.com/rust-lang/rust-bindgen/compare/v0.68.1...v0.69.0)

#### Added

- Added the `ParseCallbacks::header_file` callback which runs on every
filename passed to `Builder::header`.
- Added the `CargoCallbacks::new` constructor which emits a cargo-rerun
line
    for every input header file by default.
- Added the `CargoCallbacks::rerun_on_header_files` method to configure
whether
    a cargo-rerun line should be emitted for every input header file.

#### Changed

- The `--wrap-static-fns` feature was updated so function types that has
no
    argument use `void` as its sole argument.
-   `CargoCallbacks` is no longer a [unit-like
struct](https://doc.rust-lang.org/reference/items/structs.html) and the
`CargoCallbacks` constant was added to mitigate the breaking nature of
this
change. This constant has been marked as deprecated and users will have
to
    use the new `CargoCallbacks::new` method in the future.

#### Removed

#### Fixed

-   Allow compiling `bindgen-cli` with a static libclang.
- Emit an opaque integer type for pointer types that don't have the same
size
    as the target's pointer size.
- Avoid escaping Objective-C method names unless they are `Self`,
`self`,
    `crate` or `super`.

#### Security
