Struct rustc_const_eval::transform::promote_consts::PromoteTemps

pub struct PromoteTemps<'tcx> {
    pub promoted_fragments: Cell<IndexVec<Promoted, Body<'tcx>>>,
}

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.

Fields

promoted_fragments: Cell<IndexVec<Promoted, Body<'tcx>>>

Trait Implementations

impl<'tcx> Default for PromoteTemps<'tcx>

fn default() -> PromoteTemps<'tcx>

Returns the “default value” for a type.

impl<'tcx> MirPass<'tcx> for PromoteTemps<'tcx>

fn phase_change(&self) -> Option<MirPhase>

If this pass causes the MIR to enter a new phase, return that phase.

fn run_pass(&self, tcx: TyCtxt<'tcx>, body: &mut Body<'tcx>)

fn name(&self) -> Cow<'_, str>

fn is_enabled(&self, _sess: &Session) -> bool

Returns true if this pass is enabled with the current combination of compiler flags.

fn is_mir_dump_enabled(&self) -> bool

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.
