source · struct Promoter<'a, 'tcx> {
tcx: TyCtxt<'tcx>,
source: &'a mut Body<'tcx>,

Fields§
§tcx: TyCtxt<'tcx>
§source: &'a mut Body<'tcx>
§promoted: Body<'tcx>
§temps: &'a mut IndexVec<Local, TempState>
§extra_statements: &'a mut Vec<(Location, Statement<'tcx>)>
§keep_original: bool
If true, all nested temps are also kept in the source MIR, not moved to the promoted MIR.
Implementations§

fn is_temp_kind(&self, local: Local) -> bool
sourcefn promote_temp(&mut self, temp: Local) -> Local

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.
