Struct TyIntern

Source 
struct TyIntern<T: Clone + Eq> {
    items: Vec<T>,
    set: HashMap<T, Interned<T>>,
}
Expand description

A structure for managing the interning of values of type T.

TyIntern<T> maintains a mapping between values and their interned representations, ensuring that duplicate values are not stored multiple times.

Fields§

§items: Vec<T>§set: HashMap<T, Interned<T>>

Implementations§

Source§

impl<T: Hash + Clone + Eq> TyIntern<T>

Source

fn intern_borrow<B>(&mut self, item: &B) -> Interned<T>
where B: Eq + Hash + ToOwned<Owned = T> + ?Sized, T: Borrow<B>,

Interns a borrowed value, ensuring it is stored uniquely.

If the value has been previously interned, the same Interned<T> instance is returned.

Source

fn intern(&mut self, item: T) -> Interned<T>

Interns an owned value, storing it uniquely.

If the value has been previously interned, the existing Interned<T> is returned.

Source

fn get(&self, i: Interned<T>) -> &T

Retrieves a reference to the interned value associated with the given Interned<T> instance.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
