Struct itertools::structs::PutBack[][src]

pub struct PutBack<I> where
    I: Iterator
{ /* fields omitted */ }

An iterator adaptor that allows putting back a single item to the front of the iterator.

Iterator element type is I::Item.

Implementations

impl<I> PutBack<I> where
    I: Iterator
[src]

pub fn with_value(self, value: I::Item) -> Self[src]

put back value value (builder method)

pub fn into_parts(self) -> (Option<I::Item>, I)[src]

Split the PutBack into its parts.

pub fn put_back(&mut self, x: I::Item)[src]

Put back a single value to the front of the iterator.

If a value is already in the put back slot, it is overwritten.
