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,
impl<K, V> BoxedSlice<K, V>where
K: EntityRef,
pub unsafe fn from_raw(raw: *mut [V]) -> BoxedSlice<K, V>
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 V
s.
pub fn get_mut(&mut self, k: K) -> Option<&mut V>
pub fn get_mut(&mut self, k: K) -> Option<&mut V>
Get the element at k
if it exists, mutable version.
pub fn values_mut(&mut self) -> IterMut<'_, V> ⓘ
pub fn values_mut(&mut self) -> IterMut<'_, V> ⓘ
Iterate over all the values in this map, mutable edition.
