Function rsvg::util::utf8_cstr_bounds

pub unsafe fn utf8_cstr_bounds<'a>(
    start: *const c_char,
    end: *const c_char
) -> &'a str

Gets a known-to-be valid UTF-8 string given start/end-exclusive pointers to its bounds.

Safety: start must be a valid pointer, and end must be the same for a zero-length string, or greater than start. All the bytes between them must be valid UTF-8.
