Required methods

fn try_extend<T: IntoIterator<Item = A>>(
    &mut self,
    iter: T
) -> Result<(), Self::Err>

Extends a collection "fallibly" with the contents of an iterator.

Examples

Basic usage:

use alloc_wg::{iter::TryExtend, vec};

// You can extend a Vec<char> with some chars:
let mut message = vec!['a', 'b', 'c'];

message.try_extend(['d', 'e', 'f'].iter())?;

assert_eq!(vec!['a', 'b', 'c', 'd', 'e', 'f'], message);
