Struct bytecodec::combinator::MaybeEos

pub struct MaybeEos<D> { /* fields omitted */ }

Combinator for ignoring EOS if there is no item being decoded.

This is created by calling DecodeExt::maybe_eos.

Methods

impl<D> MaybeEos<D>

Important traits for &'a mut W

impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub fn inner_ref(&self) -> &D

Returns a reference to the inner decoder.

pub fn inner_mut(&mut self) -> &mut D

Returns a mutable reference to the inner decoder.

pub fn into_inner(self) -> D

Takes ownership of this instance and returns the inner decoder.

Trait Implementations

impl<D: Debug> Debug for MaybeEos<D>

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

Formats the value using the given formatter.

impl<D: Default> Default for MaybeEos<D>

fn default() -> MaybeEos<D>

Returns the "default value" for a type.

impl<D: Decode> Decode for MaybeEos<D>

type Item = D::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.
