Module codec

Adaptors from AsyncRead/AsyncWrite to Stream/Sink

Raw I/O objects work with byte sequences, but higher-level code usually wants to batch these into meaningful chunks, called “frames”.

Re-export of [tokio_util::codec].

Modules

length_delimited

Frame a stream of bytes based on a length prefix

Structs

AnyDelimiterCodec

A simple Decoder and Encoder implementation that splits up data into chunks based on any character in the given delimiter string.

BytesCodec

A simple Decoder and Encoder implementation that just ships bytes around.

Framed

A unified Stream and Sink interface to an underlying I/O object, using the Encoder and Decoder traits to encode and decode frames.

FramedParts

FramedParts contains an export of the data of a Framed transport. It can be used to construct a new Framed with a different codec. It contains all current buffers and the inner transport.

FramedRead

A Stream of messages decoded from an AsyncRead.

FramedWrite

A Sink of frames encoded to an AsyncWrite.

LengthDelimitedCodec

A codec for frames delimited by a frame head specifying their lengths.

LengthDelimitedCodecError

An error when the number of bytes read is more than max frame length.

LinesCodec

A simple Decoder and Encoder implementation that splits up data into lines.

Enums

AnyDelimiterCodecError

An error occurred while encoding or decoding a chunk.

LinesCodecError

An error occurred while encoding or decoding a line.

Traits

Decoder

Decoding of frames via buffers.

Encoder

Trait of helper objects to write out messages as bytes, for use with FramedWrite.
