Trait smallvec::VecLike

source · [−]

pub trait VecLike<T>: Index<usize, Output = T> + IndexMut<usize> + Index<Range<usize>, Output = [T]> + IndexMut<Range<usize>> + Index<RangeFrom<usize>, Output = [T]> + IndexMut<RangeFrom<usize>> + Index<RangeTo<usize>, Output = [T]> + IndexMut<RangeTo<usize>> + Index<RangeFull, Output = [T]> + IndexMut<RangeFull> + DerefMut<Target = [T]> + Extend<T> {
    fn push(&mut self, value: T);
}

👎 Deprecated:

Use Extend and Deref<[T]> instead

Expand description

Common operations implemented by both Vec and SmallVec.

This can be used to write generic code that works with both Vec and SmallVec.

Example

use smallvec::{VecLike, SmallVec};

fn initialize<V: VecLike<u8>>(v: &mut V) {
    for i in 0..5 {
        v.push(i);
    }
}

let mut vec = Vec::new();
initialize(&mut vec);

let mut small_vec = SmallVec::<[u8; 8]>::new();
initialize(&mut small_vec);
