type Set ¶

type Set[T comparable] map[T]struct{}

Set is a generic collection type that stores unique elements of type T.

It can be used as a replacement for map[T]struct{} with a cleaner API. The zero value (nil) is ready to use and represents an empty set.

The type implements:

• Basic operations: Add, Remove, Contains, Len, ToSlice
• Set operations: Append (union), Clone
• JSON marshaling/unmarshaling
• SQL driver.Valuer and sql.Scanner interfaces

All methods are safe to call on nil receiver and will not panic.

func NewSet[T comparable](items ...T) Set[T]

func (s *Set[T]) Add(items ...T)

func (s *Set[T]) Append(set Set[T])

func (s *Set[T]) Clone() Set[T]

func (s *Set[T]) Contains(item T) bool

func (s *Set[T]) Len() uint32

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

func (s *Set[T]) Remove(item T)

func (s *Set[T]) Reset()

func (s *Set[T]) Scan(value interface{}) error

func (s *Set[T]) ToSlice() []T

func (s *Set[T]) UnmarshalJSON(data []byte) error

func (s *Set[T]) Value() (driver.Value, error)
