Struct clippy_utils::mir::PossibleBorrowerMap

pub struct PossibleBorrowerMap<'b, 'tcx> {
    pub map: FxHashMap<Local, HybridBitSet<Local>>,
    maybe_live: ResultsCursor<'b, 'tcx, MaybeStorageLive<'tcx>>,
    pub bitset: (BitSet<Local>, BitSet<Local>),
}

Result of PossibleBorrowerVisitor.

Fields

map: FxHashMap<Local, HybridBitSet<Local>>

Mapping Local -> its possible borrowers

maybe_live: ResultsCursor<'b, 'tcx, MaybeStorageLive<'tcx>>

bitset: (BitSet<Local>, BitSet<Local>)

Implementations

impl<'a, 'b, 'tcx> PossibleBorrowerMap<'b, 'tcx>

pub fn new(cx: &'a LateContext<'tcx>, mir: &'b Body<'tcx>) -> Self

pub fn only_borrowers( &mut self, borrowers: &[Local], borrowed: Local, at: Location, ) -> bool

Returns true if the set of borrowers of borrowed living at at matches with borrowers.

pub fn bounded_borrowers( &mut self, below: &[Local], above: &[Local], borrowed: Local, at: Location, ) -> bool

Returns true if the set of borrowers of borrowed living at at includes at least below but no more than above.

pub fn local_is_alive_at(&mut self, local: Local, at: Location) -> bool

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.
