Things that can be visited by a ResultsVisitor.

This trait exists so that we can visit the results of one or more dataflow analyses simultaneously.

Required Associated Types

type Direction: Direction

type FlowState

Required Methods

fn new_flow_state(&self, body: &Body<'tcx>) -> Self::FlowState

Creates an empty FlowState to hold the transient state for these dataflow results.

The value of the newly created FlowState will be overwritten by reset_to_block_entry before it can be observed by a ResultsVisitor.

fn reset_to_block_entry(&self, state: &mut Self::FlowState, block: BasicBlock)

fn reconstruct_before_statement_effect( &mut self, state: &mut Self::FlowState, statement: &Statement<'tcx>, location: Location )

fn reconstruct_statement_effect( &mut self, state: &mut Self::FlowState, statement: &Statement<'tcx>, location: Location )

fn reconstruct_before_terminator_effect( &mut self, state: &mut Self::FlowState, terminator: &Terminator<'tcx>, location: Location )

fn reconstruct_terminator_effect( &mut self, state: &mut Self::FlowState, terminator: &Terminator<'tcx>, location: Location )
