Enum rustc_ast::ast::UseTreeKind
source · pub enum UseTreeKind {
Simple(Option<Ident>),
Nested {
items: ThinVec<(UseTree, NodeId)>,
span: Span,

Expand description
Part of use
item to the right of its prefix.
Variants§
Simple(Option<Ident>)
use prefix
or use prefix as rename
Nested
use prefix::{...}
The span represents the braces of the nested group and all elements within:
use foo::{bar, baz};
