Struct naga::arena::handle_set::HandleSet

pub struct HandleSet<T> {
    len: usize,
    members: BitSet,
    as_keys: PhantomData<T>,
}

A set of Handle<T> values.

Fields

len: usize

Bound on indexes of handles stored in this set.

members: BitSet

members[i] is true if the handle with index i is a member.

as_keys: PhantomData<T>

This type is indexed by values of type T.

Implementations

impl<T> HandleSet<T>

pub fn new() -> Self

Return a new, empty HandleSet.

pub fn for_arena(arena: &impl ArenaType<T>) -> Self

Return a new, empty HandleSet, sized to hold handles from arena.

pub fn clear(&mut self)

Remove all members from self.

pub fn clear_for_arena(&mut self, arena: &impl ArenaType<T>)

Remove all members from self, and reserve space to hold handles from arena.

pub fn all_possible(&self) -> impl Iterator<Item = Handle<T>>

Return an iterator over all handles that could be made members of this set.

pub fn insert(&mut self, handle: Handle<T>) -> bool

Add handle to the set.

Return true if handle was not already present in the set.

pub fn remove(&mut self, handle: Handle<T>) -> bool

Remove handle from the set.

Returns true if handle was present in the set.

pub fn insert_iter(&mut self, iter: impl IntoIterator<Item = Handle<T>>)

Add handles from iter to the set.

pub fn contains(&self, handle: Handle<T>) -> bool

pub fn iter(&self) -> impl '_ + Iterator<Item = Handle<T>>

Return an iterator over all handles in self.
