Struct EntitySet

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

A set of K for densely indexed entity references.

The EntitySet data structure uses the dense index space to implement a set with a bitvector. Like SecondaryMap, an EntitySet is used to associate secondary information with entities.

Implementations§

§

impl<K> EntitySet<K>
where K: EntityRef,

Shared EntitySet implementation for all value types.

pub fn new() -> EntitySet<K>

Create a new empty set.

pub fn with_capacity(capacity: usize) -> EntitySet<K>

Creates a new empty set with the specified capacity.

pub fn ensure_capacity(&mut self, capacity: usize)

Ensure that the set has enough capacity to hold capacity total elements.

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

Get the element at k if it exists.

pub fn is_empty(&self) -> bool

Is this set completely empty?

pub fn clear(&mut self)

Remove all entries from this set.

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

Iterate over all the keys in this set.

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

Insert the element at k.

pub fn pop(&mut self) -> Option<K>

Removes and returns the entity from the set if it exists.
