pub struct MaybeRequiresStorage<'mir, 'tcx> {
    body: &'mir Body<'tcx>,
    borrowed_locals: RefCell<ResultsRefCursor<'mir, 'mir, 'tcx, MaybeBorrowedLocals>>,
}
Expand description

Dataflow analysis that determines whether each local requires storage at a given location; i.e. whether its storage can go away without being observed.

Fields

body: &'mir Body<'tcx>borrowed_locals: RefCell<ResultsRefCursor<'mir, 'mir, 'tcx, MaybeBorrowedLocals>>

Implementations

Kill locals that are fully moved and have not been borrowed.

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.
