pub unsafe trait InAtomicMode: Debug { }Expand description
A marker trait for guard types that enforce the atomic mode.
Key kernel primitives such as SpinLock and Rcu rely on
the atomic mode for correctness or soundness.
The existence of such a guard guarantees that the current task is executing
in the atomic mode.
It requires core::fmt::Debug by default to make it easier to derive
Debug for types with &dyn InAtomicMode.
§Safety
The implementer must ensure that the atomic mode is maintained while the guard type is alive.
