Struct BoxedSlice

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§

§

impl<K, V> BoxedSlice<K, V>
where K: EntityRef,

pub unsafe fn from_raw(raw: *mut [V]) -> BoxedSlice<K, V>

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.

pub fn is_valid(&self, k: K) -> bool

Check if k is a valid key in the map.

pub fn get(&self, k: K) -> Option<&V>

Get the element at k if it exists.

pub fn get_mut(&mut self, k: K) -> Option<&mut V>

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

pub fn is_empty(&self) -> bool

Is this map completely empty?

pub fn len(&self) -> usize

Get the total number of entity references created.

pub fn keys(&self) -> Keys<K>

Iterate over all the keys in this map.

pub fn values(&self) -> Iter<'_, V>

Iterate over all the values in this map.

pub fn values_mut(&mut self) -> IterMut<'_, V>

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

pub fn iter(&self) -> Iter<'_, K, V>

Iterate over all the keys and values in this map.

pub fn iter_mut(&mut self) -> IterMut<'_, K, V>

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

pub fn last(&self) -> Option<&V>

Returns the last element that was inserted in the map.
