Variables

var ErrResponseNotFound = errors.New("response not found")

ErrResponseNotFound is the error when a supplied 8 ball response isn't found.

Functions

func Intn

func Intn(n uint) int

Intn returns a random number backed by `crypto/rand`.

func ResponseType

func ResponseType(r string) (int, error)

ResponseType returns whether a response is positive, neutral, or negative. Values returned are `1` for positive, `0` for neutral, and `-1` for negative.

func Shake

func Shake() string

Shake returns a Magic 8 Ball response. It returns an error if `crypto/rand` fails.

Types

type CryptoRandSource

type CryptoRandSource struct{}

CryptoRandSource is a `crypto/rand` backed source that satisfies the `math/rand.Source` interface definition. It can be used as `r := rand.New(NewCryptoRandSource())` See: https://stackoverflow.com/a/35208651/1908967

func NewCryptoRandSource

func NewCryptoRandSource() CryptoRandSource

func (CryptoRandSource) Int63

func (CryptoRandSource) Int63() int64

func (CryptoRandSource) Seed

func (CryptoRandSource) Seed(int64)
