在go中排序uint64切片

Question

I'm writing Go application using Go 1.7rc3.

I have a slice of uint64 (var dirRange []uint64) that I want to sort.

the sort package has a function sort.Ints() but it requires []int and I have []uint64.

what do I do? can I type cast the all slice ?

thanks

As of version 1.8, you can use the simpler function sort.Slice. In your case, it would be something like the following:

sort.Slice(dirRange, func(i, j int) bool { return dirRange[i] < dirRange[j] })

This avoids having to define any type just for the sorting.
