Struct tower_kafka::transport::KafkaClientCodec

pub struct KafkaClientCodec { /* private fields */ }

A simple wrapper around codec::LengthDelimitedCodec, which ensures protocol frames are well formed.

Implementations

impl KafkaClientCodec

pub fn new() -> Self

Create a new codec.

Trait Implementations

impl Debug for KafkaClientCodec

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

Formats the value using the given formatter.

impl Decoder for KafkaClientCodec

type Item = BytesMut

The type of decoded frames.

type Error = Error

The type of unrecoverable frame decoding errors.

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

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<BytesMut> for KafkaClientCodec

type Error = Error

The type of encoding errors.

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

Encodes a frame into the buffer provided.
