Trait IndexMut2

pub trait IndexMut2<I>: IndexMut<I> {
    // Required method
    fn index_mut2(
        &mut self,
        i: usize,
        j: usize,

}

Methods for simultaneously indexing a container with two distinct indices.

Required Methods

fn index_mut2( &mut self, i: usize, j: usize, ) -> (&mut Self::Output, &mut Self::Output)

Gets mutable references to two distinct elements of the container.

Panics if i == j.

Provided Methods

fn index_mut_const( &mut self, i: usize, j: usize, ) -> (&mut Self::Output, &Self::Output)

Gets a mutable reference to one element, and immutable reference to a second one.

Panics if i == j.
