Function evaluate_stencils 

pub fn evaluate_stencils(
    device: &Device,
    queue: &Queue,
    pipeline: &StencilEvalPipeline,
    gpu_table: &StencilTableGpu,
    src_buffer: &Buffer,
    dst_buffer: &Buffer,
    src_desc: BufferDescriptor,
    dst_desc: BufferDescriptor,
    batch_range: Range<u32>,
) -> Result<(), KernelError>

Available on crate feature wgpu only.

One-shot: encode, submit, and wait. The result lands in dst_buffer (which must be at least output_count * dst_desc.stride floats).
