Trait ArrayIndex

pub trait ArrayIndex<O: Object> {
    type Output;

    // Required methods
    fn get(self, array: Array<O>) -> Option<Self::Output>;
    unsafe fn get_unchecked(self, array: Array<O>) -> Self::Output;
}

A type that can be used to index into an Array.

Required Associated Types

type Output

The output returned from indexing.

Required Methods

fn get(self, array: Array<O>) -> Option<Self::Output>

Returns the output at self, or None if self is out-of-bounds.

unsafe fn get_unchecked(self, array: Array<O>) -> Self::Output

Returns the output at self without safety checks.
