Struct bytecodec::combinator::Map

pub struct Map<D, T, F> { /* fields omitted */ }

Combinator for converting decoded items to other values.

This is created by calling DecodeExt::map method.

Trait Implementations

impl<D: Debug, T: Debug, F: Debug> Debug for Map<D, T, F>

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

Formats the value using the given formatter.

impl<D, T, F> Decode for Map<D, T, F> where
    D: Decode,
    F: Fn(D::Item) -> T, 

type Item = T

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.
