Variants

ExternCrate(Option<Symbol>)

An extern crate item, with optional original crate name if the crate was renamed.

E.g., extern crate foo or extern crate foo_bar as foo.

Tuple Fields of ExternCrate

0: Option<Symbol>
Use(&'hir Path<'hir>, UseKind)

use foo::bar::*; or use foo::bar::baz as quux;

or just

use foo::bar::baz; (with as baz implicitly on the right).
