Function pineappl_grid_optimize_using 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pineappl_grid_optimize_using(
    grid: *mut Grid,
    flags: GridOptFlags,
)

Optimizes the grid representation for space efficiency. The parameter flags determines which optimizations are applied, see GridOptFlags.

Safety

If grid does not point to a valid Grid object, for example when grid is the null pointer, this function is not safe to call.
