Methods

impl Codec

pub fn new() -> Self

Trait Implementations

impl Default for Codec

fn default() -> Self

Returns the "default value" for a type.

impl Debug for Codec

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Encoder for Codec

type Item = Packet

The type of items consumed by the Encoder

type Error = ParseError

The type of encoding errors.

fn encode(
    &mut self,
    item: Self::Item,
    dst: &mut BytesMut
) -> Result<(), ParseError>

Encodes a frame into the buffer provided.

impl Decoder for Codec

type Item = Packet

The type of decoded frames.

type Error = ParseError

The type of unrecoverable frame decoding errors.

fn decode(
    &mut self,
    src: &mut BytesMut
) -> Result<Option<Self::Item>, ParseError>

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
    Self: Encoder,
    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.
