Make bindgen-cli available to product and vendor am: 76bc289dd0 am: d0ec909cc1 am: bd6f9f6a1a am: 8468220710 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/bindgen-cli/+/2476006 Change-Id: I4de8cab3b100b2dc61fca1c76ebf5fa08b55e84d Signed-off-by: Automerger Merge Worker <[email protected]>
bindgenbindgen automatically generates Rust FFI bindings to C (and some C++) libraries.
For example, given the C header doggo.h:
typedef struct Doggo { int many; char wow; } Doggo; void eleven_out_of_ten_majestic_af(Doggo* pupper);
bindgen produces Rust FFI code allowing you to call into the doggo library's functions and use its types:
/* automatically generated by rust-bindgen 0.99.9 */ #[repr(C)] pub struct Doggo { pub many: ::std::os::raw::c_int, pub wow: ::std::os::raw::c_char, } extern "C" { pub fn eleven_out_of_ten_majestic_af(pupper: *mut Doggo); }

The minimum supported Rust version is 1.60.0.
No MSRV bump policy has been established yet, so MSRV may increase in any release.
The MSRV is the minimum Rust version that can be used to compile bindgen. However, bindgen can generate bindings that are compatible with Rust versions below the current MSRV.
API reference documentation is on docs.rs
In addition to the library API and executable command-line API, bindgen can be controlled through environment variables.
End-users should set these environment variables to modify bindgen's behavior without modifying the source code of direct consumers of bindgen.
BINDGEN_EXTRA_CLANG_ARGS: extra arguments to pass to clang--sysroot=/path/to/sysroot-I"/path/with spaces"BINDGEN_EXTRA_CLANG_ARGS_<TARGET>: similar to BINDGEN_EXTRA_CLANG_ARGS, but used to set per-target arguments to pass to clang. Useful to set system include directories in a target-specific way in cross-compilation environments with multiple targets. Has precedence over BINDGEN_EXTRA_CLANG_ARGS.Additionally, bindgen uses libclang to parse C and C++ header files. To modify how bindgen searches for libclang, see the clang-sys documentation. For more details on how bindgen uses libclang, see the bindgen users guide.
We don't follow a specific release calendar, but if you need a release please file an issue requesting that (ping @emilio for increased effectiveness).
