Expand description

Lowering context for the encapsulating semantic function.

Each semantic function may generate multiple lowered functions. This context is common to all the generated lowered functions of an encapsulating semantic function.

Fields§

§db: &'db dyn LoweringGroup§semantic_function_id: FunctionWithBodyId

Id for the current function being lowered.

§function_body: Arc<FunctionBody>

Semantic model for current function body.

§semantic_defs: UnorderedHashMap<VarId, Binding>

Definitions encountered for semantic bindings. Since Constants are not lowered, this is only used for variables.

§expr_formatter: ExprFormatter<'db>

Expression formatter of the free function.

§usages: Usages

Block usages for the entire encapsulating function.

§lowerings: OrderedHashMap<GeneratedFunctionKey, FlatLowered>

Lowerings of generated functions.
