Struct cranelift_entity::EntitySet

pub struct EntitySet<K> where
    K: EntityRef,  { /* fields omitted */ }

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 EntityMap, an EntitySet is used to associate secondary information with entities.

Methods

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

Shared EntitySet implementation for all value types.

pub fn new() -> Self

Create a new empty set.

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.

Important traits for Keys<K>

impl<K: EntityRef> Iterator for Keys<K> type Item = K;

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

Iterate over all the keys in this set.

pub fn resize(&mut self, n: usize)

Resize the set to have n entries by adding default entries as needed.

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

Insert the element at k.
