Struct simple_interner::Interned

pub struct Interned<'a, T: 'a + ?Sized>(_);

An item interned by an Interner.

As two equal interned items will always be the same reference, only the reference is compared for equality rather than going to the potentially expensive implementation on the concrete type.

In all other cases, this should act as if it were a reference to the wrapped type. If you just want to get the wrapped reference out, see Interned::get.

Methods

impl<'a, T: 'a + ?Sized> Interned<'a, T>

pub fn get(this: &Self) -> &'a T

Get the wrapped reference out directly.

This is an associated fn rather than a method in order to avoid conflicting with implementations on the concrete type.
