Trait Get 

pub trait Get<Q> {
    type Key: ?Sized;
    type Output: ?Sized;

    // Required method
    fn get(&self, index: Q) -> Option<&Self::Output>
       where Self::Key: Borrow<Q>;
}

Get defines an interface for entities that can be accessed by a key; the design is similar to the Index trait in the standard library, however, uses the Borrow trait to allow for more flexible key types.

Required Associated Types

type Key: ?Sized

type Output: ?Sized

Required Methods

fn get(&self, index: Q) -> Option<&Self::Output>

where Self::Key: Borrow<Q>,

returns a reference to the element at the specified index.

Implementations on Foreign Types

impl<Q, K, U, Y> Get<Q> for &U

where U: Get<Q, Key = K, Output = Y>,

type Key = <U as Get<Q>>::Key

type Output = Y

fn get(&self, index: Q) -> Option<&<&U as Get<Q>>::Output>

where <&U as Get<Q>>::Key: Borrow<Q>,

impl<Q, T> Get<Q> for [T]

where Q: SliceIndex<[T]>,

type Key = usize

type Output = <Q as SliceIndex<[T]>>::Output

fn get(&self, index: Q) -> Option<&<[T] as Get<Q>>::Output>

where <[T] as Get<Q>>::Key: Borrow<Q>,
