Fnvk::wait_for_fences

pub unsafe fn wait_for_fences(
    device: &Device,
    fences: &[Fence],
    wait_all: bool,
    timeout_ns: u64,
) -> Result<bool, CallError>

Block until one or all of the given fences signal, or the timeout expires.

Contract

Block until one or all of the given fences signal, or the timeout expires.

Returns Ok(true) if all fences signalled within the timeout, Ok(false) if the timeout expired first.

Safety

All fences must be live handles from this device.

Fnvk::wait_for_present2_khr

pub unsafe fn wait_for_present2_khr(
    device: &Device,
    swapchain: SwapchainKHR,
    p_present_wait2_info: *const PresentWait2InfoKHR<'_>,
) -> Result<Result, CallError>

Call vkWaitForPresent2KHR using this context’s cached function pointer.

Contract

Call vkWaitForPresent2KHR using this context’s cached function pointer.

Errors

Reports a missing command or a negative native VkResult; non-error results are preserved.

Safety

The context and all handles must be live and belong to the same Vulkan implementation/device. Meet vkWaitForPresent2KHR valid usage, enabled API/extension/feature, pointer-chain lifetime, callback compatibility and host/GPU synchronization requirements. Native resources require explicit destruction after completion.

Preserves native raw pointers, explicit counts, optional nulls and return values. The caller supplies correctly aligned live storage, initialized output-chain headers and every extent implied by native counts, strides or nested records. No allocation, retry, output initialization, ownership transfer or alias fallback occurs in this wrapper. Outputs, including partial outputs on native failure, remain caller-owned and must be inspected/cleaned up according to Vulkan.
