Struct Semaphore 

pub struct Semaphore(/* private fields */);

Represents a FreeRTOS counting semaphore.

Implementations

impl Semaphore

pub fn new(max_count: u32, init_count: u32) -> Self

Creates a new semaphore. Panics on failure; see Semaphore::try_new.

pub fn try_new(max_count: u32, init_count: u32) -> Result<Self, Error>

Creates a new semaphore.

pub fn wait(&self, timeout: Duration) -> Result<(), Error>

Blocks up to timeout until an instance of the semaphore can be taken (i.e., its count decremented). If the semaphore cannot be taken (due to timeout or other reason), an error is returned.

pub fn post(&self) -> Result<(), Error>

Increments the semaphore’s count. If the semaphore cannot be given, an error is returned.

pub fn count(&self) -> u32

Gets the semaphore’s current count.
