Required Methods§

Source

fn max_payload_len(&self) -> usize

Returns the maximal length of the paylod/encoded data

Any number of calls to methods on in trait in any way should never be able to change the returned value. Only changing e.g. the charset or encoding should be able to change what max_paylod_len returns.
