Struct NullMutex 

pub struct NullMutex<T> { /* private fields */ }

“Dummy” mutex for sharing in a single task/thread.

This mutex type can be used when all bus users are contained in a single execution context. In such a situation, no actual mutex is needed, because a RefCell alone is sufficient to ensuring only a single peripheral can access the bus at the same time.

This mutex type is used with the BusManagerSimple type.

To uphold safety, this type is !Send and !Sync.
