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.
