Struct Codec 

pub struct Codec<M> { /* private fields */ }

Implementation of the tokio codec traits to encode- and decode length-prefixed postcard data as a framed stream.

Implementations

impl<M> Codec<M>

pub fn new() -> Self

pub fn max_frame_len(self, value: usize) -> Self

Trait Implementations

impl<M: Debug> Debug for Codec<M>

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

Formats the value using the given formatter.

impl<M> Decoder for Codec<M>

where M: DeserializeOwned,

type Item = M

The type of decoded frames.

type Error = CodecError

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<M> Default for Codec<M>

fn default() -> Self

Returns the “default value” for a type.

impl<M> Encoder<M> for Codec<M>

where M: Serialize,

type Error = CodecError

The type of encoding errors.

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

Encodes a frame into the buffer provided.
