Struct fluvio::dataplane::codec::FluvioCodec

pub struct FluvioCodec {}

Implement Fluvio Encoding First 4 bytes are size of the message. Then total buffer = 4 + message content

Implementations

impl FluvioCodec

pub fn new() -> FluvioCodec

Trait Implementations

impl Debug for FluvioCodec

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

Formats the value using the given formatter.

impl Decoder for FluvioCodec

type Item = BytesMut

The type of decoded frames.

type Error = Error

The type of unrecoverable frame decoding errors.

fn decode( &mut self, bytes: &mut BytesMut ) -> Result<Option<BytesMut>, <FluvioCodec as Decoder>::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 Default for FluvioCodec

fn default() -> FluvioCodec

Returns the “default value” for a type.

impl<T> Encoder<(T, i16)> for FluvioCodec

where T: Encoder,

Implement encoder for Fluvio Codec

type Error = Error

The type of encoding errors.

fn encode(&mut self, src: (T, i16), buf: &mut BytesMut) -> Result<(), Error>

Encodes a frame into the buffer provided.

impl Encoder<Bytes> for FluvioCodec

Implement encoder for Fluvio Codec This is straight pass thru, actual encoding is done file slice

type Error = Error

The type of encoding errors.

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

Encodes a frame into the buffer provided.
