Cannot get enum variant from name

[valnoel]

Hi!

I'm trying to use following helper functions to retrieve enum values from strings, but they return the enum discriminants instead:

pub fn av_color_range_from_name(name: *const libc::c_char) -> libc::c_int; // should return the AVColorRange
pub fn av_color_primaries_from_name(name: *const libc::c_char) -> libc::c_int; // should return the AVColorPrimaries
pub fn av_color_transfer_from_name(name: *const libc::c_char) -> libc::c_int; // should return the AVColorTransferCharacteristic
pub fn av_color_space_from_name(name: *const libc::c_char) -> libc::c_int; // should return the AVColorSpace
pub fn av_chroma_location_from_name(name: *const libc::c_char) -> libc::c_int; // should return the AVChromaLocation
pub fn av_stereo3d_from_name(name: *const libc::c_char) -> libc::c_int; // should return the AVStereo3DType
// maybe more...

Moreover, there is no simple way to retrieve the enum variant from the discriminant in Rust.

Would it be possible to fix these functions?

Thanks!
