Expand description

One import.

Fields§

§kind: ImportKind<'a>§root_id: NodeId

Node ID of the “root” use item – this is always the same as ImportKind’s id (if it exists) except in the case of “nested” use trees, in which case it will be the ID of the root use tree. e.g., in the example

use foo::bar::{a, b}

this would be the ID of the use foo::bar UseTree node. In case of imports without their own node ID it’s the closest node that can be used, for example, for reporting lints.

§use_span: Span

Span of the entire use statement.

§use_span_with_attributes: Span

Span of the entire use statement with attributes.

§has_attributes: bool

Did the use statement have any attributes?

§span: Span

Span of this use tree.

§root_span: Span

Span of the root use tree (see root_id).

§parent_scope: ParentScope<'a>§module_path: Vec<Segment>§imported_module: Cell<Option<ModuleOrUniformRoot<'a>>>

The resolution of module_path.

§vis: Cell<Option<Visibility>>§used: Cell<Option<Used>>
