Struct vulkano::sync::Semaphore

pub struct Semaphore<D = Arc<Device>> where
    D: SafeDeref<Target = Device>,  { /* fields omitted */ }

Used to provide synchronization between command buffers during their execution.

It is similar to a fence, except that it is purely on the GPU side. The CPU can't query a semaphore's status or wait for it to be signaled.

Implementations

impl<D> Semaphore<D> where
    D: SafeDeref<Target = Device>, 

pub fn from_pool(device: D) -> Result<Semaphore<D>, OomError>

Takes a semaphore from the vulkano-provided semaphore pool. If the pool is empty, a new semaphore will be allocated. Upon drop, the semaphore is put back into the pool.

For most applications, using the pool should be preferred, in order to avoid creating new semaphores every frame.

pub fn alloc(device: D) -> Result<Semaphore<D>, OomError>

Builds a new semaphore.

Trait Implementations

impl<D: Debug> Debug for Semaphore<D> where
    D: SafeDeref<Target = Device>, 

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DeviceOwned for Semaphore

pub fn device(&self) -> &Arc<Device>

Returns the device that owns Self.

impl<D> Drop for Semaphore<D> where
    D: SafeDeref<Target = Device>, 

pub fn drop(&mut self)

Executes the destructor for this type.

impl<D> VulkanObject for Semaphore<D> where
    D: SafeDeref<Target = Device>, 

type Object = Semaphore

The type of the object.

pub const TYPE: ObjectType

The ObjectType of the internal Vulkan handle.

pub fn internal_object(&self) -> Semaphore

Returns a reference to the object.
