One import.

Fields

kind: ImportKind<'a>

id: NodeId

The ID of the extern crate, UseTree etc that imported this Import.

In the case where the Import was expanded from a “nested” use tree, this id is the ID of the leaf tree. For example:

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

If this is the import for foo::bar::a, we would have the ID of the UseTree for a in this field.

root_id: NodeId

The id of the “root” use-kind – this is always the same as id 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 from id, this would be the ID of the use foo::bar UseTree node.

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<bool>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
