Trait std::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>;
    unsafe fn get_unchecked(self, slice: &T) -> &Self::Output;
    unsafe fn get_unchecked_mut(self, slice: &mut T) -> &mut Self::Output;
    fn index(self, slice: &T) -> &Self::Output;
    fn index_mut(self, slice: &mut T) -> &mut Self::Output;
}

🔬 This is a nightly-only experimental API. (slice_get_slice #35729)

A helper trait used for indexing operations.

Associated Types

`type Output: ?Sized`

🔬 This is a nightly-only experimental API. (slice_get_slice #35729)

The output type returned by methods.

Required Methods

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

🔬 This is a nightly-only experimental API. (slice_get_slice #35729)

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_get_slice #35729)

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_get_slice #35729)

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`

🔬 This is a nightly-only experimental API. (slice_get_slice #35729)

Returns a mutable reference to the output at this location, without performing any bounds checking.

`fn index(self, slice: &T) -> &Self::Output`

🔬 This is a nightly-only experimental API. (slice_get_slice #35729)

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`

🔬 This is a nightly-only experimental API. (slice_get_slice #35729)

Returns a mutable reference to the output at this location, panicking if out of bounds.
