Trait Superset 

pub trait Superset<S: ?Sized> { }

Implemented for any set that is a superset of set S.

Example

assert::superset::<(i32, i16), (i32,)>();
assert::superset::<(i16, i32), (i32,)>();
assert::superset::<(i32,), (i32,)>();
assert::superset::<(i32, i16), (i16, i32)>();
// assert::superset::<(i8, i16), (i32,)>(); // fails to compile

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
