Struct bytecodec::combinator::CollectN

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

Combinator for decoding the specified number of items and collecting the result.

This is created by calling DecodeExt::collectn method.

Methods

impl<D, T: Default> CollectN<D, T>

pub fn remaining_items(&self) -> usize

Returns the number of remaining items expected to be decoded.

pub fn set_remaining_items(&mut self, n: usize)

Sets the number of remaining items expected to be decoded.

Trait Implementations

impl<D: Debug, T: Debug> Debug for CollectN<D, T>

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

Formats the value using the given formatter.

impl<D: Default, T: Default> Default for CollectN<D, T>

fn default() -> CollectN<D, T>

Returns the "default value" for a type.

impl<D, T> Decode for CollectN<D, T> where     D: Decode,     T: Default + Extend<D::Item>,

type Item = T

The type of items to be decoded.

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

Consumes the given buffer (a part of a byte sequence), and proceeds the decoding process.

fn finish_decoding(&mut self) -> Result<Self::Item>

Finishes the current decoding process and returns the decoded item.

fn requiring_bytes(&self) -> ByteCount

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

fn is_idle(&self) -> bool

Returns true if there are no items to be decoded by the decoder at the next invocation of decode method, otherwise false.
