impl period has been started! Join us at Gitter.im.
bindgen automatically generates Rust FFI bindings to C and 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);
