README
This crate is useful for preventing expensive actions from taking place while adding elements to collections.
It exports a single trait, TryPush and has implementations for both Vec<T> and VecDeque<T> from the standard library.
Examples:
use try_push::*;
let mut vec = Vec::with_capacity(4);
vec.push(1);
vec.push(2);
vec.push(3);
vec.push(4); // won't reallocate
// vec.push(5); // will reallocate
assert_eq!(vec.try_push(5), Element::NotAdded(5));
