Source

pub trait ExtendFromSlice<T> {
    // Required method
    fn extend_from_slice(&mut self, other: &[T]);
}

Expand description

Trait to be implemented by a collection that can be extended from a slice

§Example

use smallvec::{ExtendFromSlice, SmallVec};

fn initialize<V: ExtendFromSlice<u8>>(v: &mut V) {
    v.extend_from_slice(b"Test!");
}

let mut vec = Vec::new();
initialize(&mut vec);
assert_eq!(&vec, b"Test!");

let mut small_vec = SmallVec::<[u8; 8]>::new();
initialize(&mut small_vec);
assert_eq!(&small_vec as &[_], b"Test!");
