Struct GpuFence 

pub struct GpuFence {
    pub id: u64,
    pub status: FenceStatus,
    pub label: Option<String>,
    /* private fields */
}

A logical GPU fence (CPU-side descriptor).

In real GPU code this would wrap a wgpu::QuerySet or a Vulkan VkFence; here it tracks status in CPU memory.

Fields

id: u64

Unique identifier.

status: FenceStatus

Current status.

label: Option<String>

Optional debug label.

Implementations

impl GpuFence

pub fn new(id: u64) -> Self

Creates a new fence in Pending state.

pub fn with_label(self, label: impl Into<String>) -> Self

Attaches a debug label.

pub fn signal(&mut self)

Signals the fence, marking GPU work as submitted.

In a real implementation this would record the fence into a command buffer; here we just record the signal time.

pub fn is_signalled(&self) -> bool

Returns true when the fence has been signalled.

pub fn reset(&mut self)

Resets the fence so it can be reused.

pub fn wait_timeout_ms(&mut self, timeout_ms: u64) -> bool

Blocks (simulated) until the fence is signalled or timeout_ms milliseconds elapse.

Returns true if the fence was already signalled (no real blocking in this CPU-only simulation).

pub fn simulated_latency(&self) -> Duration

Returns the simulated latency of this fence.

Trait Implementations

impl Clone for GpuFence

fn clone(&self) -> GpuFence

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GpuFence

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