Expand description

The embargo visitor, used to determine the exports of the AST.

Fields

tcx: TyCtxt<'tcx>access_levels: AccessLevels

Accessibility levels for reachable nodes.

macro_reachable: FxHashSet<(LocalDefId, LocalDefId)>

A set of pairs corresponding to modules, where the first module is reachable via a macro that’s defined in the second module. This cannot be represented as reachable because it can’t handle the following case:

pub mod n { // Should be Public pub(crate) mod p { // Should not be accessible pub fn f() -> i32 { 12 } // Must be Reachable } } pub macro m() { n::p::f() }

prev_level: Option<AccessLevel>

Previous accessibility level; None means unreachable.

changed: bool

Has something changed in the level map?

Implementations

Updates node level and returns the updated level.

Updates the item as being reachable through a macro defined in the given module. Returns true if the level has changed.

Trait Implementations

We want to visit items in the context of their containing module and so forth, so supply a crate for doing a deep walk.

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
Visits the top-level item and (optionally) nested items / impl items. See visit_nested_item for details. Read more
Invoked when a nested item is encountered. By default, when Self::NestedFilter is nested_filter::None, this method does nothing. You probably don’t want to override this method – instead, override Self::NestedFilter or use the “shallow” or “deep” visit patterns described on itemlikevisit::ItemLikeVisitor. The only reason to override this method is if you want a nested pattern but cannot supply a Map; see nested_visit_map for advice. Read more
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

Returns the argument unchanged.

Calls U::from(self).

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

The type returned in the event of a conversion error.
Performs the conversion.

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.
