Sampler is a golang library for sampling from a slice of items.
go get github.com/ninedraft/sampler
import "math/rand/v2"
var rnd *rand.Rand = ...
items := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}
// acquire a random subset of $items
sample := sampler.Sample(rnd, items, 3)
fmt.Println(sample)
// Output: [8 1 3]
// acquire N random choises from $items
choices := sampler.Choices(rnd, items, 3)
fmt.Println(choices)
// Output: [2 1 1]
// acquire choice a single item from $items
choice := sampler.Choice(rnd, items)
fmt.Println(choice)
// Output: 5APACHE 2.0
