pub struct SemaphoreRef<'a, System: KernelSemaphore>(_, _);
Expand description

Represents a single borrowed semaphore in a system.

This type is ABI-compatible with System::RawSemaphoreId. It’s logically equivalent to &'a Semaphore but instead stores RawSemaphoreId directly.

See Semaphore for the owned counterpart and the description of this kernel object. See SemaphoreMethods for the operations provided by this handle type.
