Required Methods§

fn expand_proc_attr_macros(&self) -> bool

Whether to expand procedural macros during name resolution.

fn set_expand_proc_attr_macros(&mut self, value__: bool)

Set the value of the expand_proc_attr_macros input.

See expand_proc_attr_macros for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

fn set_expand_proc_attr_macros_with_durability( &mut self, value: bool, durability: Durability, )

Set the value of the expand_proc_attr_macros input with a specific durability instead of the default of Durability::LOW. You can use Durability::MAX to promise that its value will never change again.

See expand_proc_attr_macros for details.

Note: Setting values will trigger cancellation of any ongoing queries; this method blocks until those queries have been cancelled.

fn file_item_tree(&self, file_id: HirFileId) -> Arc<ItemTree>

Computes an [ItemTree] for the given file or macro expansion.

fn block_item_tree(&self, block_id: BlockId) -> Arc<ItemTree>

fn file_item_tree_with_source_map( &self, file_id: HirFileId, ) -> (Arc<ItemTree>, Arc<ItemTreeSourceMaps>)

fn crate_def_map(&self, krate: Idx<CrateData>) -> Arc<DefMap>

fn block_def_map(&self, block: BlockId) -> Arc<DefMap>

Computes the block-level DefMap.

fn macro_def(&self, m: MacroId) -> MacroDefId

Turns a MacroId into a MacroDefId, describing the macro’s definition post name resolution.

fn struct_data(&self, id: StructId) -> Arc<StructData>

fn struct_data_with_diagnostics( &self, id: StructId, ) -> (Arc<StructData>, DefDiagnostics)

fn union_data(&self, id: UnionId) -> Arc<StructData>

fn body(&self, def: DefWithBodyId) -> Arc<Body>

fn expr_scopes(&self, def: DefWithBodyId) -> Arc<ExprScopes>

fn generic_params(&self, def: GenericDefId) -> Arc<GenericParams>

fn generic_params_with_source_map( &self, def: GenericDefId, ) -> (Arc<GenericParams>, Option<Arc<TypesSourceMap>>)

If this returns None for the source map, that means it is the same as with the item tree.
