Trait Backend

pub trait Backend<T: ?Sized> {
    type Symbol: BackendSymbol;

    // Required methods
    fn intern(&mut self, src: &T) -> Self::Symbol;
    fn get(&self, sym: Self::Symbol) -> Option<&T>;

    // Provided method
    unsafe fn get_unchecked(&self, sym: Self::Symbol) -> &T { ... }

Backend for the Interner

Required Associated Types

type Symbol: BackendSymbol

Required Methods

fn intern(&mut self, src: &T) -> Self::Symbol

Intern the element

fn get(&self, sym: Self::Symbol) -> Option<&T>

Resolve the symbol

Provided Methods

unsafe fn get_unchecked(&self, sym: Self::Symbol) -> &T

Resolves the symbol, without checking if it exists on the backend.

Safety

The caller must ensure that the symbol was retreived from a call to this backend’s intern function.

Implementors

impl Backend<str> for StringBuf

type Symbol = Symbol

impl<T: Clone> Backend<T> for VecBackend<T>

type Symbol = Symbol
