Enum ReplyCode 

#[repr(u8)]
pub enum ReplyCode {
    Success(SuccessReplyReason),
    Error(ErrorReplyReason),
    Unsupported = 255,
}

Enum representing reply code with reason of its creation.

Variants

Success(SuccessReplyReason)

Formats the value using the given formatter.

impl Encode for ReplyCode

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )
