Crate ax_sync 

OS-independent synchronization interfaces for TGOSKits kernels and components.

Acquisition methods state the required execution context: ordinary spin acquisitions disable preemption, *_irqsave acquisitions additionally save and disable local interrupts, and raw acquisitions require an explicit unsafe contract. [Mutex] is always sleepable and never aliases a spin lock.

Structs
