Enum rustc_codegen_llvm::debuginfo::metadata::RecursiveTypeDescription

enum RecursiveTypeDescription<'ll, 'tcx> {
    UnfinishedMetadata {
        unfinished_type: Ty<'tcx>,
        unique_type_id: UniqueTypeId,
        metadata_stub: &'ll DICompositeType,
        member_holding_stub: &'ll DICompositeType,
        member_description_factory: MemberDescriptionFactory<'ll, 'tcx>,
    },
    FinalMetadata(&'ll DICompositeType),
}

A description of some recursive type. It can either be already finished (as with FinalMetadata) or it is not yet finished, but contains all information needed to generate the missing parts of the description. See the documentation section on Recursive Types at the top of this file for more information.

Implementations

impl<'ll, 'tcx> RecursiveTypeDescription<'ll, 'tcx>

fn finalize(&self, cx: &CodegenCx<'ll, 'tcx>) -> MetadataCreationResult<'ll>

Finishes up the description of the type in question (mostly by providing descriptions of the fields of the given type) and returns the final type metadata.

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.
