Enum rustc_ast::ast::UseTreeKind

pub enum UseTreeKind {
    Simple(Option<Ident>, NodeId, NodeId),
    Nested(Vec<(UseTree, NodeId)>),
    Glob,
}

Part of use item to the right of its prefix.

Variants

Simple(Option<Ident>, NodeId, NodeId)

use prefix or use prefix as rename

The extra NodeIds are for HIR lowering, when additional statements are created for each namespace.

Tuple Fields of Simple

0: Option<Ident>1: NodeId2: NodeId

Nested(Vec<(UseTree, NodeId)>)

use prefix::{...}

Tuple Fields of Nested

0: Vec<(UseTree, NodeId)>

Glob

use prefix::*
