Required methods

fn get(self, slice: &T) -> Option<&Self::Output>

🔬 This is a nightly-only experimental API. (slice_index_methods)

Returns a shared reference to the output at this location, if in bounds.

fn get_mut(self, slice: &mut T) -> Option<&mut Self::Output>

🔬 This is a nightly-only experimental API. (slice_index_methods)

Returns a mutable reference to the output at this location, if in bounds.

unsafe fn get_unchecked(self, slice: &T) -> &Self::Output

🔬 This is a nightly-only experimental API. (slice_index_methods)
