codegen: Properly track alignment of unions. This makes us not unnecessarily add repr(align) to unions. Closes #1498.
bindgen
bindgen
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 */ #[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); }
