Struct wasmer_types::entity::SecondaryMap

source · [−]

pub struct SecondaryMap<K, V> where
    K: EntityRef,
    V: Clone,  { /* private fields */ }

Expand description

A mapping K -> V for densely indexed entity references.

The SecondaryMap data structure uses the dense index space to implement a map with a vector. Unlike PrimaryMap, an SecondaryMap can’t be used to allocate entity references. It is used to associate secondary information with entities.

The map does not track if an entry for a key has been inserted or not. Instead it behaves as if all keys have a default entry from the beginning.

Implementations

source

impl<K, V> SecondaryMap<K, V> where
K: EntityRef,
V: Clone,

source

pub fn new() -> Self where
V: Default,
