pub unsafe fn lift_str<'a>(ptr: *const u8, len: usize) -> Option<&'a str>Expand description
Borrow a (ptr, len) string parameter as a &str, validating UTF-8,
without copying.
Returns None when ptr is null but len isn’t 0, or when the bytes
aren’t valid UTF-8.
§Safety
Same contract as lift_byte_slice.
