Function wait_events 

pub fn wait_events(
    device: &DeviceFnV1_0,
    command_buffer: CommandBuffer,
    events: &[Event],
    global_barrier: Option<GlobalBarrier<'_>>,
    buffer_barriers: &[BufferBarrier<'_>],
    image_barriers: &[ImageBarrier<'_>],
)

Simplified wrapper around vkCmdWaitEvents. The mapping functions defined above are used to translate the passed in barrier definitions into a set of pipeline stages and native Vulkan memory barriers to be passed to vkCmdPipelineBarrier.

commandBuffer and events are passed unmodified to vkCmdWaitEvents.
