Trait Implementations

impl<'a, 'tcx> Analysis<'tcx> for Borrowck<'a, 'tcx>

const NAME: &'static str = "borrowck"

A descriptive name for this analysis. Used only for debugging.

type Domain = BorrowckDomain

The type that holds the dataflow state at any given point in the program.

fn bottom_value(&self, body: &Body<'tcx>) -> Self::Domain

Returns the initial value of the dataflow state upon entry to each basic block.

fn initialize_start_block(&self, _body: &Body<'tcx>, _state: &mut Self::Domain)

Mutates the initial value of the dataflow state upon entry to the START_BLOCK.

fn apply_early_statement_effect( &mut self, state: &mut Self::Domain, stmt: &Statement<'tcx>, loc: Location, )

Updates the current dataflow state with an “early” effect, i.e. one that occurs immediately before the given statement.

fn apply_primary_statement_effect( &mut self, state: &mut Self::Domain, stmt: &Statement<'tcx>, loc: Location, )

Updates the current dataflow state with the effect of evaluating a statement.

fn apply_early_terminator_effect( &mut self, state: &mut Self::Domain, term: &Terminator<'tcx>, loc: Location, )

Updates the current dataflow state with an effect that occurs immediately before the given terminator.

fn apply_primary_terminator_effect<'mir>( &mut self, state: &mut Self::Domain, term: &'mir Terminator<'tcx>, loc: Location, ) -> TerminatorEdges<'mir, 'tcx>

Updates the current dataflow state with the effect of evaluating a terminator.

fn apply_call_return_effect( &mut self, _state: &mut Self::Domain, _block: BasicBlock, _return_places: CallReturnPlaces<'_, 'tcx>, )

Updates the current dataflow state with the effect of a successful return from a Call terminator.

type Direction = Forward

The direction of this analysis. Either Forward or Backward.

type SwitchIntData = !

Auxiliary data used for analyzing SwitchInt terminators, if necessary.

fn get_switch_int_data( &mut self, _block: BasicBlock, _discr: &Operand<'tcx>, ) -> Option<Self::SwitchIntData>

Used to update the current dataflow state with the effect of taking a particular branch in a SwitchInt terminator.

fn apply_switch_int_edge_effect( &mut self, _data: &mut Self::SwitchIntData, _state: &mut Self::Domain, _edge: SwitchIntTarget, )

See comments on get_switch_int_data.

impl<'a, 'tcx> ResultsVisitor<'a, 'tcx, Borrowck<'a, 'tcx>> for MirBorrowckCtxt<'a, '_, 'tcx>

fn visit_after_early_statement_effect( &mut self, _results: &mut Results<'tcx, Borrowck<'a, 'tcx>>, state: &BorrowckDomain, stmt: &'a Statement<'tcx>, location: Location, )

Called after the “early” effect of the given statement is applied to state.

fn visit_after_early_terminator_effect( &mut self, _results: &mut Results<'tcx, Borrowck<'a, 'tcx>>, state: &BorrowckDomain, term: &'a Terminator<'tcx>, loc: Location, )

Called after the “early” effect of the given terminator is applied to state.

fn visit_after_primary_terminator_effect( &mut self, _results: &mut Results<'tcx, Borrowck<'a, 'tcx>>, state: &BorrowckDomain, term: &'a Terminator<'tcx>, loc: Location, )

Called after the “primary” effect of the given terminator is applied to state.

fn visit_block_start(&mut self, _state: &<A as Analysis<'tcx>>::Domain)

fn visit_after_primary_statement_effect( &mut self, _results: &mut Results<'tcx, A>, _state: &<A as Analysis<'tcx>>::Domain, _statement: &'mir Statement<'tcx>, _location: Location, )

Called after the “primary” effect of the given statement is applied to state.

fn visit_block_end(&mut self, _state: &<A as Analysis<'tcx>>::Domain)

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.
