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

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§

source§

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

source

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.

source

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

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.
