}

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<'ra>>

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: CmRefCell<FxIndexMap<BindingKey, &'ra CmRefCell<NameResolution<'ra>>>>

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.

underscore_disambiguator: CmCell<u32>

Used to disambiguate underscore items (const _: T = ...) in the module.

unexpanded_invocations: CmRefCell<FxHashSet<LocalExpnId>>

Macro invocations that can expand into items in this module.

no_implicit_prelude: bool

Whether #[no_implicit_prelude] is active.

glob_importers: CmRefCell<Vec<Interned<'ra, ImportData<'ra>>>>

globs: CmRefCell<Vec<Interned<'ra, ImportData<'ra>>>>

traits: CmRefCell<Option<Box<[(Macros20NormalizedIdent, Interned<'ra, NameBindingData<'ra>>, Option<Module<'ra>>)]>>>

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

self_binding: Option<Interned<'ra, NameBindingData<'ra>>>

Binding for implicitly declared names that come with a module, like self (not yet used), or crate/$crate (for root modules).

Implementations

impl<'ra> ModuleData<'ra>

pub(crate) fn new( parent: Option<Module<'ra>>, kind: ModuleKind, expansion: ExpnId, span: Span, no_implicit_prelude: bool, self_binding: Option<Interned<'ra, NameBindingData<'ra>>>, ) -> Self

Trait Implementations

impl Hash for ModuleData<'_>

fn hash<H>(&self, _: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
