Types

type Set

type Set struct {
	// contains filtered or unexported fields
}

Set is a set of strings that is comparable with == and !=. The zero value is a valid and empty set.

func SetOf

func SetOf(elems ...string) (s Set)

SetOf returns a new Set containing the provided elements.

func (*Set) Add

func (s *Set) Add(elems ...string)

Add turns s into the union of s and the provided elements.

func (Set) Cardinality

func (s Set) Cardinality() int

Cardinality returns the number of elements in s. It is more efficient than computing the length of the slice returned by ToSlice.

func (Set) MarshalJSON

func (s Set) MarshalJSON() ([]byte, error)

func (Set) ToSlice

func (s Set) ToSlice() []string

ToSlice returns a sorted slice of the elements in s.

func (*Set) UnmarshalJSON

func (s *Set) UnmarshalJSON(b []byte) error
