pub struct DecoderMap<D, F> { /* private fields */ }

A decoder for applying a non-fallible transformation on the success type.

The result of crate::decode::DecoderExt::map.

Trait Implementations

impl<D: Debug, F: Debug> Debug for DecoderMap<D, F>

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

Formats the value using the given formatter.

impl<D, F, A, B, E> Decoder for DecoderMap<D, F>

where D: Decoder<Item = A, Error = E>, F: Fn(A) -> B, E: From<Error>,

type Item = B

The type of decoded frames.

type Error = E

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.
