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.

Source§fn is_required(&self) -> bool
fn is_required(&self) -> bool
Returns
true if this pass must be run (i.e. it is required for soundness).
For passes which are strictly optimizations, this should return false.
If this is false, #[optimize(none)] will disable the pass.fn name(&self) -> &'static str

fn is_enabled(&self, _sess: &Session) -> bool
Returns
true if this pass is enabled with the current combination of compiler flags.Source§fn can_be_overridden(&self) -> bool
fn can_be_overridden(&self) -> bool
Returns
true if this pass can be overridden by -Zenable-mir-passes. This should be
true for basically every pass other than those that are necessary for correctness.fn is_mir_dump_enabled(&self) -> bool
