Struct unsigned_varint::codec::UviBytes

pub struct UviBytes<T = Bytes> { /* fields omitted */ }

Encoder/Decoder of unsigned-varint, length-prefixed bytes

Implementations

impl<T> UviBytes<T>

pub fn set_max_len(&mut self, val: usize)

Limit the maximum allowed length of bytes.

pub fn max_len(&self) -> usize

Return the maximum allowed number of bytes to encode/decode.

Trait Implementations

impl<T> Decoder for UviBytes<T>

type Item = BytesMut

The type of decoded frames.

type Error = Error

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, 

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> Decoder for UviBytes<T>

type Item = BytesMut

The type of items returned by decode

type Error = Error

The type of decoding errors.

fn decode(
    &mut self,
    src: &mut BytesMut
) -> Result<Option<Self::Item>, Self::Error>

Decode an item from the src BytesMut into an item

fn decode_eof(
    &mut self,
    src: &mut BytesMut
) -> Result<Option<Self::Item>, Self::Error>

Called when the input stream reaches EOF, signaling a last attempt to decode

impl<T> Default for UviBytes<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Buf> Encoder for UviBytes<T>

type Item = T

The type of items consumed by encode

type Error = Error

The type of encoding errors.

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

Encodes an item into the BytesMut provided by dst.

impl<T: Buf> Encoder<T> for UviBytes<T>

type Error = Error

The type of encoding errors.

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

Encodes a frame into the buffer provided.
