Struct RespCodec 

pub struct RespCodec { /* private fields */ }

Tokio-util codec for RESP2/RESP3 framing.

A single instance manages one connection’s protocol state. Call set_version after a successful HELLO 3 handshake to switch to RESP3.

Implementations

impl RespCodec

pub fn new(version: Version) -> Self

pub fn resp2() -> Self

pub fn resp3() -> Self

pub fn with_max_frame_bytes(self, limit: usize) -> Self

pub fn set_version(&mut self, version: Version)

Switch protocol version mid-stream (e.g. after HELLO 3 succeeds).

pub fn version(&self) -> Version

Trait Implementations

impl Clone for RespCodec

fn clone(&self) -> RespCodec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RespCodec

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

Formats the value using the given formatter.

impl Decoder for RespCodec

type Item = Value

The type of decoded frames.

type Error = RespError

The type of unrecoverable frame decoding errors.

fn decode(&mut self, src: &mut BytesMut) -> Result<Option<Value>, RespError>

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 RespCodec

fn default() -> Self

Returns the “default value” for a type.

impl Encoder<&Value> for RespCodec

type Error = RespError

The type of encoding errors.

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

Encodes a frame into the buffer provided.

impl Encoder<Value> for RespCodec

type Error = RespError

The type of encoding errors.

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

Encodes a frame into the buffer provided.
