pub struct BoxedSlice<K, V>where
    K: EntityRef,
{ /* private fields */ }
Expand description

A slice mapping K -> V allocating dense entity references.

The BoxedSlice data structure uses the dense index space to implement a map with a boxed slice.

Implementations

Create a new slice from a raw pointer. A safer way to create slices is to use PrimaryMap::into_boxed_slice().

Safety

This relies on raw pointing to a valid slice of Vs.

Check if k is a valid key in the map.

Get the element at k if it exists.

Get the element at k if it exists, mutable version.

Is this map completely empty?

Get the total number of entity references created.

Iterate over all the keys in this map.

Iterate over all the values in this map.

Iterate over all the values in this map, mutable edition.

Iterate over all the keys and values in this map.

Iterate over all the keys and values in this map, mutable edition.

Returns the last element that was inserted in the map.
