Struct rustc_const_eval::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>,
extra_statements: &'a mut Vec<(Location, Statement<'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
sourceimpl<'a, 'tcx> Promoter<'a, 'tcx>
impl<'a, 'tcx> Promoter<'a, 'tcx>
fn new_block(&mut self) -> BasicBlock

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