Function wasmer_types::lib::std::iter::chain

pub fn chain<A, B>(
    a: A,
    b: B,
) -> Chain<<A as IntoIterator>::IntoIter, <B as IntoIterator>::IntoIter> 
where
    A: IntoIterator,
    B: IntoIterator<Item = <A as IntoIterator>::Item>,

🔬This is a nightly-only experimental API. (iter_chain)

Available on crate feature std only.

Converts the arguments to iterators and links them together, in a chain.

See the documentation of Iterator::chain for more.

Examples

#![feature(iter_chain)]

use std::iter::chain;

let a = [1, 2, 3];
let b = [4, 5, 6];

let mut iter = chain(a, b);

assert_eq!(iter.next(), Some(1));
assert_eq!(iter.next(), Some(2));
assert_eq!(iter.next(), Some(3));
assert_eq!(iter.next(), Some(4));
assert_eq!(iter.next(), Some(5));
assert_eq!(iter.next(), Some(6));
assert_eq!(iter.next(), None);
