Struct clippy_utils::mir::possible_origin::PossibleOriginVisitor
source · pub(super) struct PossibleOriginVisitor<'a, 'tcx> {
possible_origin: TransitiveRelation,
body: &'a Body<'tcx>,
}
Expand description
Collect possible borrowed for every &mut
local.
For example, _1 = &mut _2
generate _1: {_2,…}
Known Problems: not sure all borrowed are tracked
Fields§
§possible_origin: TransitiveRelation
§body: &'a Body<'tcx>

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.
