Function mxr_uid_from_string 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn mxr_uid_from_string(
    text: *const c_char,
    out: *mut mxr_uid_t,
) -> mxr_result_t

Reads the dotted-hex form mxr_uid_to_string() writes.

Safety

text points at a NUL-terminated string and out at a writable mxr_uid_t.
