Attribute Macro proof

#[proof]

Marks a Kani proof harness

For async harnesses, this will call block_on to drive the future to completion (see its documentation for more information).

If you want to spawn tasks in an async harness, you have to pass a schedule to the #[kani::proof] attribute, e.g. #[kani::proof(schedule = kani::RoundRobin::default())].

This will wrap the async function in a call to block_on_with_spawn (see its documentation for more information).
