Crate eternal_iterator 

This crate provides EternalIterator, which promises that the iterator iterates forever.

This crate is compatible with core::iter. So you can use methods in core::iter to generate iterators.

let mut it = core::iter::repeat(123_i32).map(|i| i * 2)
		.enumerate().skip(5).step_by(2).zip(core::iter::once(3).chain(10..));
assert_eq!(it.next_eternal(), ((5, 246), 3));
assert_eq!(it.next_eternal(), ((7, 246), 10));
assert_eq!(it.next(), Some(((9, 246), 11)));
assert_eq!(it.next_eternal(), ((11, 246), 12));

Structs

FromFn

It is used on the implementation of from_fn(). See from_fn() document for details.

Successors

It is used on the implementation of successors(). See successors() document for details.

UnsafeWrapper

It is used on the implementation of wrap_unsafe(). See wrap_unsafe() document for details.

Traits

EternalIterator

Like Iterator, but promises that the iterator iterates forever.

Functions

from_fn

Creates a new iterator where each iteration calls the provided closure F: FnMut() -> T.

successors

Creates a new iterator where each successive item is computed based on the preceding one.

wrap

Safe version of wrap_unsafe()

wrap_unsafe^⚠

Wraps Iterator to be seen as EternalIterator.
