pub struct Interner<T>(/* private fields */)
where
T: 'static + ?Sized;
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§
§impl<T> Interner<T>where
T: Internable + ?Sized,
impl<T> Interner<T>where
T: Internable + ?Sized,
pub fn intern(&self, value: &T) -> Interned<T>
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.
