Function calls format

[dineshadepu]

Hello all,

I am using RustFmt for code refactor. I have an issue with function calls with many arguments.
Say, I have a function

linear_viscoelastic_model_dem_other(                                                                                                                                         
            &mut grains,                                                                                                                                                             
            &mut hopper,                                                                                                                                                             
            1e7,                                                                                                                                                                     
            0.0,                                                                                                                                                                     
            dt,                                                                                                                                                                      
            stage2,                                                                                                                                                                  
            &grid,                                                                                                                                                                   
            dim,
 );    

I want this to be

linear_viscoelastic_mode_dem_other(
         &mut grains, &mut hopper, 1e7, 0.0,
         dt, stage2, &grid, dim);
