Expand description
Data structure that holds context for performing the information flow analysis.
Fields§
§tcx: TyCtxt<'tcx>
The type context used for the analysis.
def_id: DefId
The ID of the body being analyzed.
body: &'a Body<'tcx>
The body being analyzed.
place_info: PlaceInfo<'a, 'tcx>
The metadata about places used in the analysis.
Implementations§
source§impl<'a, 'tcx> FlowAnalysis<'a, 'tcx>
impl<'a, 'tcx> FlowAnalysis<'a, 'tcx>
sourcepub fn new(
tcx: TyCtxt<'tcx>,
def_id: DefId,
body: &'a Body<'tcx>,
place_info: PlaceInfo<'a, 'tcx>
) -> Self
pub fn new( tcx: TyCtxt<'tcx>, def_id: DefId, body: &'a Body<'tcx>, place_info: PlaceInfo<'a, 'tcx> ) -> Self
Constructs (but does not execute) a new FlowAnalysis.
sourcepub fn location_domain(&self) -> &Rc<LocationOrArgDomain>
pub fn location_domain(&self) -> &Rc<LocationOrArgDomain>
Returns the LocationOrArgDomain
used by the analysis.
sourcepub fn deps_for(
&self,
state: &FlowDomain<'tcx>,
place: Place<'tcx>
) -> LocationOrArgSet
pub fn deps_for( &self, state: &FlowDomain<'tcx>, place: Place<'tcx> ) -> LocationOrArgSet
Returns all the dependencies of place
within state
.
Prefer using this method instead of accessing FlowDomain
directly,
unless you really know what you’re doing.
