Struct Fence 

pub struct Fence {
    pub device: Device,
    pub handle: Fence,
    pub timestamps: TimestampQueryPool,
    /* private fields */
}

Represents a Vulkan fence used to track queue submission completion.

See VkFence.

Fields

device: Device

The device which owns this fence resource.

Note: This field is read-only.

handle: Fence

The native Vulkan fence handle.

Note: This field is read-only.

timestamps: TimestampQueryPool

Timestamp query results for queued work once this fence has signaled.

Note: This field is read-only.

Implementations

impl Fence

pub fn create(device: &Device, signaled: bool) -> Result<Self, DriverError>

Creates a Vulkan fence owned by device.

See vkCreateFence.

pub fn status(&self) -> Result<bool, DriverError>

Returns true if this fence is signaled.

Signaled deferred payloads are released before this returns Ok(true).

See vkGetFenceStatus.

pub fn is_queued(&self) -> bool

Returns true if work has been queued against this fence.

pub fn reset(&mut self) -> Result<&mut Self, DriverError>

Resets this fence to the unsignaled state.

If queued work has already signaled, deferred payloads are released before the fence is reset.

See vkResetFences.

pub fn wait(&mut self) -> Result<&mut Self, DriverError>

Waits for this fence to signal, then releases deferred payloads.

See vkWaitForFences.

Trait Implementations

impl Debug for Fence

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

Formats the value using the given formatter.

impl Drop for Fence

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
