Implementations§

source§

impl<'mir, 'tcx, A, D> Engine<'mir, 'tcx, A>
where A: Analysis<'tcx, Domain = D>, D: Clone + JoinSemiLattice,

source

pub(crate) fn new( tcx: TyCtxt<'tcx>, body: &'mir Body<'tcx>, analysis: A, ) -> Self

Creates a new Engine to solve a dataflow problem with an arbitrary transfer function.

source

pub fn pass_name(self, name: &'static str) -> Self

Adds an identifier to the graphviz output for this particular run of a dataflow analysis.

Some analyses are run multiple times in the compilation pipeline. Give them a pass_name to differentiate them. Otherwise, only the results for the latest run will be saved.

source

pub fn iterate_to_fixpoint(self) -> Results<'tcx, A>
where A::Domain: DebugWithContext<A>,

Computes the fixpoint for this dataflow problem and returns it.
