Struct litep2p::codec::unsigned_varint::UnsignedVarint

pub struct UnsignedVarint { /* private fields */ }

Unsigned varint codec.

Implementations

impl UnsignedVarint

pub fn new(max_size: Option<usize>) -> Self

Create new UnsignedVarint codec.

pub fn with_max_size(max_size: usize) -> Self

Set maximum size for encoded/decodes values.

pub fn encode<T: Into<Bytes>>(payload: T) -> Result<Vec<u8>>

Encode payload using unsigned-varint.

pub fn decode(payload: &mut BytesMut) -> Result<BytesMut>

Decode payload into BytesMut.

Trait Implementations

impl Decoder for UnsignedVarint

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, 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 Encoder<Bytes> for UnsignedVarint

type Error = Error

The type of encoding errors.

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

Encodes a frame into the buffer provided.
