Struct Codec

pub struct Codec<D, E> { /* private fields */ }

JSON-based codec.

Implementations

impl<D, E> Codec<D, E>

pub fn new(pretty: bool) -> Self

Creates a new Codec.

pretty controls whether or not encoded values are pretty-printed.

pub fn pretty(&mut self, pretty: bool)

Set whether or not encoded values are pretty-printed.

Trait Implementations

impl<D: Clone, E: Clone> Clone for Codec<D, E>

fn clone(&self) -> Codec<D, E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<D: Debug, E: Debug> Debug for Codec<D, E>

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

Formats the value using the given formatter.

impl<D, E> Decoder for Codec<D, E>

where for<'de> D: Deserialize<'de>,

type Item = D

The type of decoded frames.

type Error = Error

The type of unrecoverable frame decoding errors.

fn decode(&mut self, src: &mut BytesMut) -> Result<Option<D>, 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 + Encoder,

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<D, E> Default for Codec<D, E>

fn default() -> Self

Returns the “default value” for a type.

impl<D, E> Encoder for Codec<D, E>

where E: Serialize,

type Item = E

The type of items consumed by the Encoder

type Error = Error

The type of encoding errors.

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

Encodes a frame into the buffer provided.
