Trait Implementations

impl<'mir, 'tcx> ResultsVisitor<'mir, 'tcx, Results<'tcx, ValueAnalysisWrapper<ConstAnalysis<'_, 'tcx>>, IndexVec<BasicBlock, State<FlatSet<Scalar<AllocId>>>>>> for Collector<'tcx, '_>

type FlowState = State<FlatSet<Scalar<AllocId>>>

fn visit_statement_before_primary_effect( &mut self, results: &mut Results<'tcx, ValueAnalysisWrapper<ConstAnalysis<'_, 'tcx>>>, state: &Self::FlowState, statement: &'mir Statement<'tcx>, location: Location )

Called with the before_statement_effect of the given statement applied to state but not its statement_effect.

fn visit_statement_after_primary_effect( &mut self, results: &mut Results<'tcx, ValueAnalysisWrapper<ConstAnalysis<'_, 'tcx>>>, state: &Self::FlowState, statement: &'mir Statement<'tcx>, location: Location )

Called with both the before_statement_effect and the statement_effect of the given statement applied to state.

fn visit_terminator_before_primary_effect( &mut self, results: &mut Results<'tcx, ValueAnalysisWrapper<ConstAnalysis<'_, 'tcx>>>, state: &Self::FlowState, terminator: &'mir Terminator<'tcx>, location: Location )

Called with the before_terminator_effect of the given terminator applied to state but not its terminator_effect.

fn visit_block_start( &mut self, _results: &mut R, _state: &Self::FlowState, _block_data: &'mir BasicBlockData<'tcx>, _block: BasicBlock )

fn visit_terminator_after_primary_effect( &mut self, _results: &mut R, _state: &Self::FlowState, _terminator: &'mir Terminator<'tcx>, _location: Location )

Called with both the before_terminator_effect and the terminator_effect of the given terminator applied to state.

fn visit_block_end( &mut self, _results: &mut R, _state: &Self::FlowState, _block_data: &'mir BasicBlockData<'tcx>, _block: BasicBlock )

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.
