Implementations

impl<'tcx> LoanKillsGenerator<'_, 'tcx>

fn record_killed_borrows_for_place( &mut self, place: Place<'tcx>, location: Location )

Records the borrows on the specified place as killed. For example, when assigning to a local, or on a call’s return destination.

fn record_killed_borrows_for_local(&mut self, local: Local, location: Location)

Records the borrows on the specified local as killed.

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.
