Single,

ListStem,
}
Variants§
Single
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
Glob import, e.g., use foo::*
.
ListStem
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.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
