Types

type Set

type Set map[string]struct{}

Set is a nifty little wrapper for common set operations on a map. Because it is equivalent to a map, make/range/len will still work with Set.

func New

func New(xs ...string) Set

New creates a new Set with xs.

func (Set) Add

func (s Set) Add(x string)

Add adds x to s.

func (Set) Has

func (s Set) Has(x string) bool

Has returns true if x is in s.

func (Set) Remove

func (s Set) Remove(x string)

Remove removes x from s.

func (Set) ToSlice

func (s Set) ToSlice() []string

ToSlice converts s to a slice.
