Struct cuprate_levin::codec::LevinMessageCodec

pub struct LevinMessageCodec<T: LevinBody> { /* private fields */ }

A tokio-codec for levin messages or in other words the decoded body of a levin bucket.

Trait Implementations

impl<T: Clone + LevinBody> Clone for LevinMessageCodec<T>

where T::Command: Clone,

fn clone(&self) -> LevinMessageCodec<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + LevinBody> Debug for LevinMessageCodec<T>

where T::Command: Debug,

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

Formats the value using the given formatter.

impl<T: LevinBody> Decoder for LevinMessageCodec<T>

type Item = T

The type of decoded frames.

type Error = BucketError

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<T: LevinBody> Default for LevinMessageCodec<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: LevinBody> Encoder<LevinMessage<T>> for LevinMessageCodec<T>

type Error = BucketError

The type of encoding errors.

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

Encodes a frame into the buffer provided.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
