Struct OffloadManifestDecoder 

pub(crate) struct OffloadManifestDecoder<'a, 'tcx> {
    decoder: MemDecoder<'a>,
    type_shorthands: Lock<FxHashMap<usize, Ty<'tcx>>>,
    predicate_shorthands: Lock<FxHashMap<usize, PredicateKind<'tcx>>>,
    tcx: TyCtxt<'tcx>,
    def_path_map: Lock<Option<FxHashMap<(Symbol, String), DefId>>>,
}

Decoder used to read the offload monomorphization manifest.

Fields

decoder: MemDecoder<'a>

type_shorthands: Lock<FxHashMap<usize, Ty<'tcx>>>

predicate_shorthands: Lock<FxHashMap<usize, PredicateKind<'tcx>>>

tcx: TyCtxt<'tcx>

def_path_map: Lock<Option<FxHashMap<(Symbol, String), DefId>>>

Map from (crate name, DefPath string) to DefId, used to resolve DefIds across compilation sessions where StableCrateId differs.

Implementations

impl<'a, 'tcx> OffloadManifestDecoder<'a, 'tcx>

pub(crate) fn new(data: &'a [u8], tcx: TyCtxt<'tcx>) -> Result<Self, ()>

fn get_or_build_def_path_map(&self) -> FxHashMap<(Symbol, String), DefId>

(crate name, DefPath) -> DefId map for resolving cross-session DefIds.

fn build_def_path_map(tcx: TyCtxt<'tcx>) -> FxHashMap<(Symbol, String), DefId>

Build a (crate name, DefPath) -> DefId map. Owns the format details.

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.
