Struct State

pub(super) struct State {
    pub qualif: MixedBitSet<Local>,
    pub borrow: MixedBitSet<Local>,
}

The state for the FlowSensitiveAnalysis dataflow analysis. This domain is likely homogeneous, and has a big size, so we use a bitset that can be sparse (c.f. issue #134404).

Fields

qualif: MixedBitSet<Local>

Describes whether a local contains qualif.

borrow: MixedBitSet<Local>

Describes whether a local’s address escaped and it might become qualified as a result an indirect mutation.

Implementations

impl State

pub(super) fn contains(&self, local: Local) -> bool

Trait Implementations

impl Clone for State

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, other: &Self)

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C> DebugWithContext<C> for State

fn fmt_with(&self, ctxt: &C, f: &mut Formatter<'_>) -> Result

fn fmt_diff_with(&self, old: &Self, ctxt: &C, f: &mut Formatter<'_>) -> Result

Print the difference between self and old.

impl JoinSemiLattice for State

fn join(&mut self, other: &Self) -> bool

Computes the least upper bound of two elements, storing the result in self and returning true if self has changed.

impl PartialEq for State

fn eq(&self, other: &State) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for State

impl StructuralPartialEq for State

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
