Trait AppendCopy

pub trait AppendCopy<T>
where
    T: Copy,
{
    // Required method
    fn append_copy(&mut self, i: &[T]);
}

Collections that support extending themselves mutably from copyable slices

Required Methods

fn append_copy(&mut self, i: &[T])

Extend self mutably, copying from a slice.

Worst-case implementations copy 1 element at a time (time O(n))

Best-case implementations copy as much of the origin slice at once as possible (system word size), e.g. Vec::append. (still linear time, but on 64-bit systems this is 64 times faster than a 1-by-1 copy.)
