Trait Semaphore 

pub trait Semaphore<T, E>
where
    T: ResourceMan<E>,
    E: Copy + Clone,
{
    // Required methods
    fn p(&self) -> Option<E>;
    fn v(&self, e: E);
    fn is_empty(&self) -> bool;
    fn is_full(&self) -> bool;

    // Provided methods
    unsafe fn p_unguarded(&self) -> Option<E> { ... }
    unsafe fn v_unguarded(&self, e: E) { ... }
}

Required Methods

fn p(&self) -> Option<E>

Probeer (try): the consumer end, tries to get resource, blocks on empty

fn v(&self, e: E)

Verhoog (increment): the producer end, increments the resource and must not block

fn is_empty(&self) -> bool

must not block

fn is_full(&self) -> bool

must not block

Provided Methods

unsafe fn p_unguarded(&self) -> Option<E>

if the semaphore is also to be accessed in the epilogue level, the L2 lock is already acquired.

unsafe fn v_unguarded(&self, e: E)

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
