Auto merge of #1441 - scoopr:fix_namespace_macro, r=emilio Fix namespaces with macro names This fixes 1. When the name of the namespace is actually a `#define` macro, which previosly got the name of the macro 2. When the namespace is started from a included file (the header is wrapped in a `nsbegin.h`/`nsend.h` includes), which previously got generated name for the namespace The change is small, but I feel it is a bit of a hack. It wasn't obvious to me what is a better path though.
bindgenimpl 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); }
