Struct rustc_mir_transform::sroa::ReplacementVisitor

struct ReplacementVisitor<'tcx, 'll> {
    tcx: TyCtxt<'tcx>,
    local_decls: &'ll LocalDecls<'tcx>,
    replacements: ReplacementMap<'tcx>,
    all_dead_locals: BitSet<Local>,
    fragments: IndexVec<Local, Vec<(&'tcx [PlaceElem<'tcx>], Local)>>,
}

Fields

tcx: TyCtxt<'tcx>

local_decls: &'ll LocalDecls<'tcx>

This is only used to compute the type for VarDebugInfoContents::Composite.

replacements: ReplacementMap<'tcx>

Work to do.

all_dead_locals: BitSet<Local>

This is used to check that we are not leaving references to replaced locals behind.

fragments: IndexVec<Local, Vec<(&'tcx [PlaceElem<'tcx>], Local)>>

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

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.
