Function cmd_set_stencil_reference 

pub unsafe fn cmd_set_stencil_reference(
    device: &Device,
    command_buffer: CommandBuffer,
    face_mask: StencilFaceFlags,
    reference: u32,
) -> Result<(), CallError>

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