Struct rustc_mir::transform::generator::GeneratorSavedLocals

struct GeneratorSavedLocals(BitSet<Local>);

The set of Locals that must be saved across yield points.

GeneratorSavedLocal is indexed in terms of the elements in this set; i.e. GeneratorSavedLocal::new(1) corresponds to the second local included in this set.

Implementations

impl GeneratorSavedLocals

fn iter_enumerated(
    &self
) -> impl '_ + Iterator<Item = (GeneratorSavedLocal, Local)>

Returns an iterator over each GeneratorSavedLocal along with the Local it corresponds to.

fn renumber_bitset(&self, input: &BitSet<Local>) -> BitSet<GeneratorSavedLocal>

Transforms a BitSet<Local> that contains only locals saved across yield points to the equivalent BitSet<GeneratorSavedLocal>.

fn get(&self, local: Local) -> Option<GeneratorSavedLocal>

Methods from Deref<Target = BitSet<Local>>

pub fn domain_size(&self) -> usize

Gets the domain size.

pub fn count(&self) -> usize

Count the number of set bits in the set.

pub fn contains(&self, elem: T) -> bool

Returns true if self contains elem.

pub fn superset(&self, other: &BitSet<T>) -> bool

Is self is a (non-strict) superset of other?

pub fn is_empty(&self) -> bool

Is the set empty?

pub fn words(&self) -> &[u64]

Gets a slice of the underlying words.

pub fn iter(&self) -> BitIter<'_, T>

Iterates over the indices of set bits in a sorted order.

pub fn to_hybrid(&self) -> HybridBitSet<T>

Duplicates the set as a hybrid set.

Trait Implementations

impl Deref for GeneratorSavedLocals

type Target = BitSet<Local>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
