4 public declarations with native signatures and source-owned contracts.

FnRustExperimental

Fnvk::flush_mapped_memory_ranges

pub unsafe fn flush_mapped_memory_ranges(
    device: &Device,
    ranges: &[MappedMemoryRange<'_>],
) -> Result<(), CallError>

Flush mapped memory ranges to make host writes visible to the device.

Contract

Flush mapped memory ranges to make host writes visible to the device.

Required for non-host-coherent memory types before GPU reads.

Safety

All ranges must be within currently mapped memory objects.

Khronos reference: vkFlushMappedMemoryRanges

Fnvk::free_command_buffers

pub unsafe fn free_command_buffers(
    device: &Device,
    pool: CommandPool,
    buffers: &[CommandBuffer],
) -> Result<(), CallError>

Free command buffers back to their pool.

Contract

Free command buffers back to their pool.

Safety

All buffers must have finished execution on the GPU.

Khronos reference: vkFreeCommandBuffers

Fnvk::free_descriptor_sets

pub unsafe fn free_descriptor_sets(
    device: &Device,
    descriptor_pool: DescriptorPool,
    descriptor_sets: &[DescriptorSet],
) -> Result<(), CallError>

Call vkFreeDescriptorSets using this context’s cached function pointer.

Contract

Call vkFreeDescriptorSets using this context’s cached function pointer.

Errors

Reports a missing command, invalid slice lengths/counts or a native error.

Safety

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

Khronos reference: vkFreeDescriptorSets

Fnvk::free_memory

pub unsafe fn free_memory(
    device: &Device,
    memory: DeviceMemory,
    allocator: Option<&AllocationCallbacks>,
) -> Result<(), CallError>

Free a previously allocated device memory object.

Contract

Free a previously allocated device memory object.

Safety

All resources bound to this memory must have been destroyed. The memory must not be freed more than once.

Khronos reference: vkFreeMemory
