pub fn new(max_payload_size: usize) -> Self

Trait Implementations

impl Decoder for MqttCodec

type Item = Packet

The type of decoded frames.

type Error = Error

The type of unrecoverable frame decoding errors.

fn decode(&mut self, buf: &mut BytesMut) -> Result<Option<Packet>, Error>

Attempts to decode a frame from the provided buffer of bytes.

fn decode_eof(
    &mut self,
    buf: &mut BytesMut
) -> Result<Option<Self::Item>, Self::Error>

A default method available to be called when there are no more bytes available to be read from the underlying I/O.

fn framed<T>(self, io: T) -> Framed<T, Self> where
    T: AsyncRead + AsyncWrite, 

Provides a [Stream] and [Sink] interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

impl Encoder<Packet> for MqttCodec

type Error = Error

The type of encoding errors.

fn encode(&mut self, msg: Packet, buf: &mut BytesMut) -> Result<(), Error>

Encodes a frame into the buffer provided.
