Struct rustc_mir_transform::promote_consts::Promoter
source · struct Promoter<'a, 'tcx> {
tcx: TyCtxt<'tcx>,
source: &'a mut Body<'tcx>,
promoted: Body<'tcx>,
temps: &'a mut IndexVec<Local, TempState>,

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>)>
§required_consts: Vec<ConstOperand<'tcx>>
Used to assemble the required_consts list while building the promoted.
keep_original: bool
If true, all nested temps are also kept in the source MIR, not moved to the promoted MIR.
add_to_required: bool
If true, add the new const (the promoted) to the required_consts of the parent MIR.
This is initially false and then set by the visitor when it encounters a Call
terminator.
