Function create_compute_pipeline_array 

pub unsafe fn create_compute_pipeline_array<const N: usize>(
    device: VkHandleRef<'_, VkDevice>,
    pipeline_cache: Option<VkHandleRef<'_, VkPipelineCache>>,
    create_infos: &[ComputePipelineCreateInfo<'_>; N],
    allocation_callbacks: Option<&VkAllocationCallbacks>,
) -> Result<[VkPipeline; N]>

Safety

pipeline_cache must be created from device.
