#[no_mangle] pub unsafe extern "C" fn encoder_max_buffer_length_from_utf16_if_no_unmappables(
encoder: *const Encoder,
u16_length: usize
) -> usize
Query the worst-case output size when encoding from UTF-16 with replacement.
Returns the size of the output buffer in bytes that will not overflow
given the current state of the encoder and u16_length
number of
additional input code units if there are no unmappable characters in
the input or SIZE_MAX
if size_t
would overflow.
