Automatically generates Rust FFI bindings to C (and some C++) libraries.
bors-servo Auto merge of #1391 - emilio:u128, r=fitzgen
codegen: Generate u128 / i128 when available.

This is the first step to fix #1370 / #1338 / etc.

Fix for that will build up on this.

bindgen

impl period has been started! Join us at Gitter.im.

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);
}
