You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: arguments.rs
    path of file: ./repos/accel/accel-derive/tests/kernels
    
    the code of the file until where you have to start completion: //! Testing launch arguments are correctly handled

use acce
    
fn test() -> Result<()> {
    let device = Device::nth(0)?;
    let ctx = device.create_context();
    let i = 12;
    let grid = Grid::x(1);
    let block = Block::x(4);
    launch(&ctx, grid, block, (i,))?;
    Ok(())
}
