Required Methods
fn get(self, slice: &[T]) -> Option<&Self::Output>
Returns a shared reference to the output at this location, if in bounds.
fn get_mut(self, slice: &mut [T]) -> Option<&mut Self::Output>
Returns a mutable reference to the output at this location, if in bounds.
unsafe fn get_unchecked(self, slice: &[T]) -> &Self::Output
Returns a shared reference to the output at this location, without performing any bounds checking.
unsafe fn get_unchecked_mut(self, slice: &mut [T]) -> &mut Self::Output
Returns a mutable reference to the output at this location, without performing any bounds checking.
fn index(self, slice: &[T]) -> &Self::Output
Returns a shared reference to the output at this location, panicking if out of bounds.
fn index_mut(self, slice: &mut [T]) -> &mut Self::Output
Returns a mutable reference to the output at this location, panicking if out of bounds.
