pub unsafe fn select_implementation(impl_: SimdImpl)Expand description
Force the use of a particular CPU instruction set, globally.
The default behavior is to automatically select, which should normally work best. But this function may be used to force a lower instruction set for test and benchmarking purposes, or if one of the higher level optimizations does not work well.
