Outputs

parenting: FxHashMap<LocalDefId, ItemLocalId>parent_node: ItemLocalId

The parent of this node

owner: LocalDefIddefinitions: &'a Definitions

Implementations

Trait Implementations

Because we want to track parent items and so forth, enable deep walking so that we walk nested items in the context of their outer items.

Like visit_nested_item(), but for trait items. See visit_nested_item() for advice on when to override this method. Read more
Like visit_nested_item(), but for impl items. See visit_nested_item() for advice on when to override this method. Read more
Like visit_nested_item(), but for foreign items. See visit_nested_item() for advice on when to override this method. Read more
Invoked to visit the body of a function, method or closure. Like visit_nested_item, does nothing by default unless you override Self::NestedFilter. Read more
Visits the top-level item and (optionally) nested items / impl items. See visit_nested_item for details. Read more
Override this type to control which nested HIR are visited; see NestedFilter for details. If you override this type, you must also override nested_visit_map. Read more
If type NestedFilter is set to visit nested items, this method must also be overridden to provide a map to retrieve nested items. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

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.
