Trait Implementations

impl Deref for Collection

type Target = Data

The resulting type after dereferencing.

fn deref(&self) -> &<Collection as Deref>::Target

Dereferences the value.

impl DerefMut for Collection

fn deref_mut(&mut self) -> &mut <Collection as Deref>::Target

Mutably dereferences the value.
