Trait Internable

pub trait Internable: Hash + Eq {
    // Required methods
    fn leak(&self) -> &'static Self;
    fn ref_eq(&self, other: &Self) -> bool;
    fn ref_hash<H: Hasher>(&self, state: &mut H);
}

A trait for internable values.

This is used by Interner<T> to create static references for values that are interned.

Required Methods

fn leak(&self) -> &'static Self

Creates a static reference to self, possibly leaking memory.

fn ref_eq(&self, other: &Self) -> bool

Returns true if the two references point to the same value.

fn ref_hash<H: Hasher>(&self, state: &mut H)

Feeds the reference to the hasher.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
