Provided Methods

fn visit_block_start(&mut self, _state: &Self::Domain)

fn visit_statement_before_primary_effect( &mut self, _results: &mut R, _state: &Self::Domain, _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 R, _state: &Self::Domain, _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 R, _state: &Self::Domain, _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_terminator_after_primary_effect( &mut self, _results: &mut R, _state: &Self::Domain, _terminator: &'mir Terminator<'tcx>, _location: Location, )

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

The call_return_effect (if one exists) will not be applied to state.

fn visit_block_end(&mut self, _state: &Self::Domain)
