Expand description

One node in the tree of modules.

Note that a “module” in resolve is broader than a mod that you declare in Rust code. It may be one of these:

  • mod
  • crate root (aka, top-level anonymous module)
  • enum
  • trait
  • curly-braced block with statements

You can use ModuleData::kind to determine the kind of module this is.

Fields§

§parent: Option<Module<'a>>

The direct parent module (it may not be a mod, however).

§kind: ModuleKind

What kind of module this is, because this may not be a mod.

§lazy_resolutions: RefCell<FxIndexMap<BindingKey, &'a RefCell<NameResolution<'a>>>>

Mapping between names and their (possibly in-progress) resolutions in this module. Resolutions in modules from other crates are not populated until accessed.

§populate_on_access: Cell<bool>

True if this is a module from other crate that needs to be populated on access.

§unexpanded_invocations: RefCell<FxHashSet<LocalExpnId>>

Macro invocations that can expand into items in this module.

§no_implicit_prelude: bool

Whether #[no_implicit_prelude] is active.

§glob_importers: RefCell<Vec<Interned<'a, ImportData<'a>>>>§globs: RefCell<Vec<Interned<'a, ImportData<'a>>>>§traits: RefCell<Option<Box<[(Ident, Interned<'a, NameBindingData<'a>>)]>>>

Used to memoize the traits in this module for faster searches through all traits in scope.

§span: Span

Span of the module itself. Used for error reporting.

§expansion: ExpnId
