Trait collections::slice::SliceIndex
pub trait SliceIndex<T> where T: ?Sized, {
type Output: ?Sized;
fn get(self, slice: &T) -> Option<&Self::Output>;
fn get_mut(self, slice: &mut T) -> Option<&mut Self::Output>;

fn index(self, slice: &T) -> &Self::Output;
fn index_mut(self, slice: &mut T) -> &mut Self::Output;
}
A helper trait used for indexing operations.
Associated Types
type Output: ?Sized
The output type returned by methods.
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.
