Module semaphore 

Semaphores

Semaphores are synchronization primitives that allow threads to coordinate their execution. They are used to control access to a shared resource by limiting the number of threads that can access it simultaneously.

esp-radio sometimes mixes up semaphores and mutexes (FreeRTOS allows this), so this crate exposes a single interface to work with both.

Implementation

Implement the SemaphoreImplementation trait for an object, and use the register_semaphore_implementation to register that implementation for esp-radio.

See the SemaphoreImplementation documentation for more information.

Usage

Users should use SemaphoreHandle to interact with semaphores created by the driver implementation. Use SemaphoreKind to specify the type of semaphore or mutex to create.

Note that the only expected user of this crate is esp-radio.
