Expand description
A fence is used to know when a command buffer submission has finished its execution.
When a command buffer accesses a resource, you have to ensure that the CPU doesn’t access the same resource simultaneously (except for concurrent reads). Therefore in order to know when the CPU can access a resource again, a fence has to be used.
Implementations
sourceimpl<D> Fence<D>where
D: SafeDeref<Target = Device>,
impl<D> Fence<D>where
D: SafeDeref<Target = Device>,
sourcepub fn from_pool(device: D) -> Result<Fence<D>, OomError>
pub fn from_pool(device: D) -> Result<Fence<D>, OomError>
Takes a fence from the vulkano-provided fence pool.
If the pool is empty, a new fence will be allocated.
Upon drop
, the fence is put back into the pool.
For most applications, using the fence pool should be preferred, in order to avoid creating new fences every frame.
sourcepub fn alloc_signaled(device: D) -> Result<Fence<D>, OomError>
pub fn alloc_signaled(device: D) -> Result<Fence<D>, OomError>
Builds a new fence in signaled state.
sourcepub fn wait(&self, timeout: Option<Duration>) -> Result<(), FenceWaitError>
pub fn wait(&self, timeout: Option<Duration>) -> Result<(), FenceWaitError>
Waits until the fence is signaled, or at least until the timeout duration has elapsed.
Returns Ok
if the fence is now signaled. Returns Err
if the timeout was reached instead.
If you pass a duration of 0, then the function will return without blocking.
