Required Methods§

Source

spec fn obeys_sub_assign_spec() -> bool

Source

spec fn sub_assign_req(&self, rhs: Rhs) -> bool

Source

spec fn sub_assign_spec(&self, rhs: Rhs) -> &Self

Source

exec fn sub_assign(&mut self, rhs: Rhs)

requires
self.sub_assign_req(rhs),
ensures
Self::obeys_sub_assign_spec() ==> &*final(self) == old(self).sub_assign_spec(rhs),

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
