Trait Metadata

pub(super) trait Metadata<'a, 'tcx>: Copy {
    // Required method
    fn blob(self) -> &'a MetadataBlob;

    // Provided methods
    fn cdata(self) -> Option<CrateMetadataRef<'a>> { ... }
    fn sess(self) -> Option<&'tcx Session> { ... }
    fn tcx(self) -> Option<TyCtxt<'tcx>> { ... }
    fn decoder(self, pos: usize) -> DecodeContext<'a, 'tcx> { ... }
}

Abstract over the various ways one can create metadata decoders.
