Types ¶
type Set ¶
type Set[T constraints.Ordered] map[T]Empty
Set is a set of comparable types, implemented via map[T]struct{} for minimal memory consumption.
func KeySet ¶
func KeySet[T constraints.Ordered](theMap interface{}) Set[T]
KeySet creates a Set from the keys of a map[T](? extends interface{}). If the value passed in is not actually a map, this will panic.
func New ¶
func New[T constraints.Ordered](items ...T) Set[T]
New creates a set from a list of values.
func (Set[T]) Difference ¶
Difference returns a set of objects that are not in s2 For example: s1 = {a1, a2, a3} s2 = {a1, a2, a4, a5} s1.Difference(s2) = {a3} s2.Difference(s1) = {a4, a5}
func (Set[T]) Equal ¶
Equal returns true if and only if s1 is equal (as a set) to s2. Two sets are equal if their membership is identical. (In practice, this means same elements, order doesn't matter)
func (Set[T]) Intersection ¶
Intersection returns a new set which includes the item in BOTH s1 and s2 For example: s1 = {a1, a2} s2 = {a2, a3} s1.Intersection(s2) = {a2}
func (Set[T]) IsSuperset ¶
IsSuperset returns true if and only if s1 is a superset of s2.
func (Set[T]) Union ¶
Union returns a new set which includes items in either s1 or s2. For example: s1 = {a1, a2} s2 = {a3, a4} s1.Union(s2) = {a1, a2, a3, a4} s2.Union(s1) = {a1, a2, a3, a4}
func (*Set[T]) UnmarshalJSON ¶
func (Set[T]) UnsortedList ¶
func (s Set[T]) UnsortedList() []T
UnsortedList returns the slice with contents in random order.
