pub struct Intern<K: EntityRef, V> { /* private fields */ }
Expand description
A helper structure to “intern” and deduplicate values of type V
with an
identifying key K
.
Note that this can also be used where V
can’t be intern’d to represent a
flat list of items.
Implementations§
source§impl<K, V> Intern<K, V>where
K: EntityRef,
impl<K, V> Intern<K, V>where
K: EntityRef,
sourcepub fn push(&mut self, value: V) -> K
pub fn push(&mut self, value: V) -> K
Inserts the value
specified into this set, returning either a fresh
key K
if this value hasn’t been seen before or otherwise returning the
previous K
used to represent value.
Note that this should only be used for component model items where the
creation of value
is not side-effectful.
