pub(crate) struct PromoteTemps<'tcx> {
pub promoted_fragments: Cell<IndexVec<Promoted, Body<'tcx>>>,
}Expand description
A MirPass for promotion.
Promotion is the extraction of promotable temps into separate MIR bodies so they can have
'static lifetime.
After this pass is run, promoted_fragments will hold the MIR body corresponding to each
newly created Constant.
