Struct cranelift_entity::EntitySet
source · [−]pub struct EntitySet<K> where
K: EntityRef, { /* private fields */ }
Expand description
A set of K
for densely indexed entity references.
The EntitySet
data structure uses the dense index space to implement a set with a bitvector.
Like SecondaryMap
, an EntitySet
is used to associate secondary information with entities.
Implementations
sourceimpl<K> EntitySet<K> where
K: EntityRef,
impl<K> EntitySet<K> where
K: EntityRef,
Shared EntitySet
implementation for all value types.
sourcepub fn with_capacity(capacity: usize) -> Self
pub fn with_capacity(capacity: usize) -> Self
Creates a new empty set with the specified capacity.
sourcepub fn cardinality(&self) -> usize
pub fn cardinality(&self) -> usize
Returns the cardinality of the set. More precisely, it returns the number of calls to
insert
with different key values, that have happened since the the set was most recently
clear
ed or created with new
.

pub fn keys(&self) -> Keys<K>ⓘNotable traits for Keys<K>impl<K: EntityRef> Iterator for Keys<K> type Item = K;
Iterate over all the keys in this set.
