source in use prefix::source as target.

target: Ident

target in use prefix::source as target.

source_bindings: PerNS<Cell<Result<&'a NameBinding<'a>, Determinacy>>>

Bindings to which source refers to.

target_bindings: PerNS<Cell<Option<&'a NameBinding<'a>>>>

type_ns_only: bool

true for ...::{self [as target]} imports, false otherwise.
