• Signal - Signalling latest value to a single consumer.
• Watch - Signalling latest value to multiple consumers.
• Mutex - Mutex for synchronizing state between asynchronous tasks.
• Pipe - Byte stream implementing embedded_io traits.
• WakerRegistration - Utility to register and wake a Waker.
• AtomicWaker - A variant of WakerRegistration accessible using a non-mut API.
• MultiWakerRegistration - Utility registering and waking multiple Waker's.
• LazyLock - A value which is initialized on the first access
