Trait Implementations

impl<'tcx> AnalysisDomain<'tcx> for MaybeStorageLive

type Domain = BitSet<Local>

The type that holds the dataflow state at any given point in the program.

const NAME: &'static str

A descriptive name for this analysis. Used only for debugging.

fn bottom_value(&self, body: &Body<'tcx>) -> Self::Domain

The initial value of the dataflow state upon entry to each basic block.

fn initialize_start_block(&self, body: &Body<'tcx>, on_entry: &mut Self::Domain)

Mutates the initial value of the dataflow state upon entry to the START_BLOCK.

type Direction: Direction = Forward

The direction of this analysis. Either Forward or Backward.

impl Clone for MaybeStorageLive

fn clone(&self) -> MaybeStorageLive

Returns a copy of the value.
