Struct wasmer_types::entity::PrimaryMap [−][src]
pub struct PrimaryMap<K, V> where
K: EntityRef, { /* fields omitted */ }
Expand description
A primary mapping K -> V
allocating dense entity references.
The PrimaryMap
data structure uses the dense index space to implement a map with a vector.
A primary map contains the main definition of an entity, and it can be used to allocate new
entity references with the push
method.
There should only be a single PrimaryMap
instance for a given EntityRef
type, otherwise
conflicting references will be created. Using unknown keys for indexing will cause a panic.
Note that PrimaryMap
doesn’t implement Deref
or DerefMut
, which would allow
&PrimaryMap<K, V>
to convert to &[V]
. One of the main advantages of PrimaryMap
is
that it only allows indexing with the distinct EntityRef
key type, so converting to a
plain slice would make it easier to use incorrectly. To make a slice of a PrimaryMap
, use
into_boxed_slice
.
