Struct bytecodec::combinator::AndThen

pub struct AndThen<D0, D1, F> { /* fields omitted */ }

Combinator for conditional decoding.

If the first item is successfully decoded, it will start decoding the second item by using the decoder returned by f function.

This is created by calling DecodeExt::and_then method.

Trait Implementations

impl<D0: Debug, D1: Debug, F: Debug> Debug for AndThen<D0, D1, F>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<D0, D1, F> Decode for AndThen<D0, D1, F> where
    D0: Decode,
    D1: Decode,
    F: Fn(D0::Item) -> D1, 

type Item = D1::Item

The type of items to be decoded.

fn decode(
    &mut self,
    buf: &[u8],
    eos: Eos
) -> Result<(usize, Option<Self::Item>)>

Consumes the given buffer (a part of a byte sequence), and decodes an item from it.

fn requiring_bytes(&self) -> ByteCount

Returns the lower bound of the number of bytes needed to decode the next item.
