Struct rustc_mir_transform::sroa::ReplacementMap

struct ReplacementMap<'tcx> {
    fragments: IndexVec<Local, Option<IndexVec<FieldIdx, Option<(Ty<'tcx>, Local)>>>>,
}

Fields

fragments: IndexVec<Local, Option<IndexVec<FieldIdx, Option<(Ty<'tcx>, Local)>>>>

Pre-computed list of all “new” locals for each “old” local. This is used to expand storage and deinit statement and debuginfo.

Implementations

impl<'tcx> ReplacementMap<'tcx>

fn replace_place( &self, tcx: TyCtxt<'tcx>, place: PlaceRef<'tcx> ) -> Option<Place<'tcx>>

fn place_fragments( &self, place: Place<'tcx> ) -> Option<impl Iterator<Item = (FieldIdx, Ty<'tcx>, Local)> + '_>

Trait Implementations

impl<'tcx> Debug for ReplacementMap<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx> Default for ReplacementMap<'tcx>

fn default() -> ReplacementMap<'tcx>

Returns the “default value” for a type.

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.
