pub enum RafxFence {
Empty(RafxFenceEmpty),
}
Expand description
A GPU -> CPU synchronization mechanism.
A fence can be in the following states:
- Unsubmitted - Initial state when created
- Incomplete - Once a command buffer is submitted, the fence is marked as incomplete
- Complete - The GPU can mark a fence as complete to signal completion of work.
The status of the fence returns to Unsubmitted when get_fence_status() is called while in a completed state. In other words, the Complete status can only be returned one time unless the fence is submitted again.
Fences must not be dropped if they are in use by the GPU.

Implementations§
source§impl RafxFence
impl RafxFence
sourcepub fn get_fence_status(&self) -> RafxResult<RafxFenceStatus>
pub fn get_fence_status(&self) -> RafxResult<RafxFenceStatus>
Get the status of the fence. See RafxFenceStatus
The status of the fence returns to Unsubmitted when get_fence_status() is called while in a completed state. In other words, the Complete status can only be returned one time unless the fence is submitted again.
sourcepub fn wait(&self) -> RafxResult<()>
pub fn wait(&self) -> RafxResult<()>
Wait for the fence to be signaled as complete by the GPU
sourcepub fn empty_fence(&self) -> Option<&RafxFenceEmpty>
pub fn empty_fence(&self) -> Option<&RafxFenceEmpty>
Get the underlying metal API object. This provides access to any internally created metal objects.
