impl<'tcx, 'a> AnalysisDomain<'tcx> for MaybeStorageDead<'a>

type Domain = BitSet<Local>

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

const NAME: &'static str = "maybe_storage_dead"

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

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

Returns 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 = Forward

The direction of this analysis. Either Forward or Backward.

impl<'a> Clone for MaybeStorageDead<'a>

fn clone(&self) -> MaybeStorageDead<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

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.
