Overview ¶
rand2 is a drop-in replacement for the "math/rand" package. It initializes the global random generator with a random seed (instead of 1), and provides additional functionality over the standard "math/rand" package.

Functions ¶
func JitterFraction ¶
Uniformly jitters the provided duration by +/- the given fraction. NOTE: fraction must be in (0, 1].
func PickN ¶
func PickN(population []interface{}, n int) (
picked []interface{}, remaining []interface{}, err error)
Same as 'Sample' except it returns both the 'picked' sample set and the 'remaining' elements.
