Functions ¶
func FilterSlice ¶
func LimitSlice ¶
func Pointer ¶
func Pointer[T any](v T) *T
Pointer creates a pointer from the given value. This is useful, when creating a pointer from a loop variable 1 or when creating a pointer from a return value of another function, since both would require assigning the value to an intermediate variable first.
Types ¶
type Set ¶
type Set[T constraints.Ordered] struct { // contains filtered or unexported fields }
Set implements a set data structure based on built-in maps. This is not optimized for large data, but to be convient.
func NewSet ¶
func NewSet[T constraints.Ordered](values ...T) *Set[T]
NewSet initializes a new Set with the given values. If there are no values provides this is equivalent to new(Set[T]).
func SetIntersect ¶
func SetIntersect[T constraints.Ordered](sets ...*Set[T]) *Set[T]
SetIntersect returns a set that only contains elements which exist in all sets.
func (*Set[T]) Add ¶
func (s *Set[T]) Add(value T)
Add puts a single value to the set. The set will be the same, if it already contains the value.
func (Set[T]) MarshalJSON ¶
MarshalJSON adds support for mashaling the set into a JSON list.
func (*Set[T]) Remove ¶
func (s *Set[T]) Remove(value T)
Remove removes the given value from the set. The set will be the same, if the value is not part of it.
func (*Set[T]) ToList ¶
func (s *Set[T]) ToList() []T
ToList converts the set into a slice. Since the set uses a map as an underlying data structure, this will copy each value. So it might be memory intensive. Also it sorts the slice to ensure a cosistent result.
func (*Set[T]) UnmarshalJSON ¶
MarshalJSON adds support for unmashaling the set from a JSON list.
