Struct rustc_codegen_llvm::debuginfo::metadata::type_map::TypeMap

pub(crate) struct TypeMap<'ll, 'tcx> {
    pub(super) unique_id_to_di_node: RefCell<FxHashMap<UniqueTypeId<'tcx>, &'ll DIType>>,
}

The TypeMap is where the debug context holds the type metadata nodes created so far. The debuginfo nodes are identified by UniqueTypeId.

Fields

unique_id_to_di_node: RefCell<FxHashMap<UniqueTypeId<'tcx>, &'ll DIType>>

Implementations

impl<'ll, 'tcx> TypeMap<'ll, 'tcx>

pub(super) fn insert( &self, unique_type_id: UniqueTypeId<'tcx>, metadata: &'ll DIType )

Adds a UniqueTypeId to metadata mapping to the TypeMap. The method will fail if the mapping already exists.

pub(super) fn di_node_for_unique_id( &self, unique_type_id: UniqueTypeId<'tcx> ) -> Option<&'ll DIType>

Trait Implementations

impl<'ll, 'tcx> Default for TypeMap<'ll, 'tcx>

fn default() -> TypeMap<'ll, '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.
