Functions ¶
func AlphaString ¶
AlphaString returns a random alphanumeric string n characters long.
func AlphaStringRange ¶
AlphaRange returns a random alphanumeric string at least min and no more than max characters long.
func ChoiceString ¶
ChoiceString returns a random selection from an array of strings.
func FolderSize ¶
func NamespaceKey ¶
func PathFolders ¶
func SignString ¶
Types ¶
type AtomicInt64 ¶
type AtomicInt64 struct {
// contains filtered or unexported fields
}
func NewAtomicInt64 ¶
func NewAtomicInt64(init int64) *AtomicInt64
func (*AtomicInt64) Caculate ¶
func (ai *AtomicInt64) Caculate(delta int64) int64
func (*AtomicInt64) Value ¶
func (ai *AtomicInt64) Value() int64
type Background ¶
func (*Background) Work ¶
func (b *Background) Work(fn func())
type Choice ¶
type Choice struct {
Weight int
Item interface{}
}
A Choice contains a generic item and a weight controlling the frequency with which it will be selected.
func WeightedChoice ¶
WeightedChoice used weighted random selection to return one of the supplied choices. Weights of 0 are never selected. All other weight values are relative. E.g. if you have two choices both weighted 3, they will be returned equally often; and each will be returned 3 times as often as a choice weighted 1.
type Email ¶
type Email struct {
*Match
}
func ValidEmail ¶
func ValidEmail() Email
func (Email) DefaultMessage ¶
type Length ¶
type Length struct {

}
Requires an array or string to be at most a given length.
func ValidMaxSize ¶
func (*MaxSize) DefaultMessage ¶
func (*MaxSize) IsSatisfied ¶
type MinSize ¶
type MinSize struct {
Min int
}
Requires an array or string to be at least a given length.
