Struct Fence

pub struct Fence<B: Backend> { /* private fields */ }

Fence wrapper.

Implementations

impl<B> Fence<B>

where B: Backend,

pub fn device_id(&self) -> DeviceId

Get owned id.

pub fn assert_device_owner(&self, device: &Device<B>)

Assert specified device is owner.

pub fn instance_id(&self) -> InstanceId

Get owned id.

pub fn assert_instance_owner(&self, instance: &Instance<B>)

Assert specified instance is owner.

impl<B> Fence<B>

where B: Backend,

pub fn new(device: &Device<B>, signaled: bool) -> Result<Self, OutOfMemory>

Create new fence in signaled or unsignaled state.

pub fn is_submitted(&self) -> bool

Check if fence was submitted.

pub fn is_signaled(&self) -> bool

Check if fence is signaled.

pub fn is_unsignaled(&self) -> bool

Check if fence is unsignaled. It can be submitted as well.

pub fn reset(&mut self, device: &Device<B>) -> Result<(), OutOfMemory>

Reset signaled fence. Panics if not signaled. Becomes unsigneled.

pub unsafe fn mark_reset(&mut self)

Mark signaled fence as reset. Panics if not signaled. Becomes unsigneled. Fence must be reset using raw fence value.

pub unsafe fn mark_signaled(&mut self) -> FenceEpoch

Mark fence as signaled. Panics if not submitted. Fence must be checked to be signaled using raw fence value.

pub fn wait_signaled( &mut self, device: &Device<B>, timeout_ns: u64, ) -> Result<Option<FenceEpoch>, OomOrDeviceLost>

Wait for fence to become signaled. Panics if not submitted. Returns submission epoch on success.

pub fn check_signaled( &mut self, device: &Device<B>, ) -> Result<Option<FenceEpoch>, DeviceLost>

Check if fence has became signaled. Panics if not submitted. Returns submission epoch on success.

pub fn raw(&self) -> &B::Fence

Get raw fence reference. Use mark_* functions to reflect stage changes.

pub fn epoch(&self) -> FenceEpoch

Get submission epoch. Panics if not submitted.

pub fn into_inner(self) -> B::Fence

Unwrap raw fence value. Panics if submitted.

impl<B: Debug + Backend> Debug for Fence<B>

where B::Fence: Debug,

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

Formats the value using the given formatter.
