as in enum Foo { Bar(..) }
.
Unit variant.
E.g., Bar = ..
as in enum Foo { Bar = .. }
.
Return the fields of this variant.

of this variant’s constructor, if it has one.
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.
