Variants
One import, e.g., use foo::bar
or use foo::bar as baz
.
Also produced for each element of a list use
, e.g.
use foo::{a, b}
lowers to use foo::a; use foo::b;
.
Glob import, e.g., use foo::*
.
Degenerate list import, e.g., use foo::{a, b}
produces
an additional use foo::{}
for performing checks such as
unstable feature gating. May be removed in the future.
