Struct Interner

Source

pub struct Interner<T: ?Sized + 'static>(/* private fields */);

Expand description

A thread-safe interner which can be used to create Interned<T> from &T

For details on interning, see the module level docs.

The implementation ensures that two equal values return two equal Interned<T> values.

To use an Interner<T>, T must implement Internable.

Implementations§

Source §

impl<T: ?Sized> Interner<T>

Source

pub const fn new() -> Self

Creates a new empty interner

Source §

impl<T: Internable + ?Sized> Interner<T>

Source

pub fn intern(&self, value: &T) -> Interned<T>

Return the Interned<T> corresponding to value.

If it is called the first time for value, it will possibly leak the value and return an Interned<T> using the obtained static reference. Subsequent calls for the same value will return Interned<T> using the same static reference.

Trait Implementations§

fn default() -> Self

Returns the “default value” for a type. Read more

Immutably borrows from an owned value. Read more

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
