Function destroy_query_pool 

pub unsafe fn destroy_query_pool(
    device: &Device,
    query_pool: QueryPool,
    allocator: Option<&AllocationCallbacks>,
) -> Result<(), CallError>

Call vkDestroyQueryPool 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 vkDestroyQueryPool valid usage, enabled API/extension/feature, pointer-chain lifetime, callback compatibility and host/GPU synchronization requirements. Native resources require explicit destruction after completion.
