Expand description

The definition table containing node definitions. It holds the DefPathTable for LocalDefIds/DefPaths. It also stores mappings to convert LocalDefIds to/from HirIds.

Fields

table: DefPathTablenext_disambiguator: FxHashMap<(LocalDefId, DefPathData), u32>expansions_that_defined: FxHashMap<LocalDefId, ExpnId>

Item with a given LocalDefId was defined during macro expansion with ID ExpnId.

def_id_to_span: IndexVec<LocalDefId, Span>stable_crate_id: StableCrateId

The StableCrateId of the local crate.

Implementations

Gets the number of definitions.

Returns the path from the crate root to index. The root nodes are not included in the path (i.e., this will be an empty vector for the crate root). For an inlined item, this will be the path of the item in the external crate (but the path will begin with the path to the external crate).

Adds a root definition (no parent) and a few other reserved definitions.

Adds a definition with a parent definition.

Retrieves the span of the given DefId if DefId is in the local crate.
