Functions

func List 

func List[T ordered](s Set[T]) []T

List returns the contents as a sorted T slice.

This is a separate function and not a method because not all types supported by Generic are ordered and only those can be sorted.

Types

type Byte deprecated 

type Byte map[byte]Empty

Byte is a set of bytes, implemented via map[byte]struct{} for minimal memory consumption.

Deprecated: use generic Set instead. new ways: s1 := Set[byte]{} s2 := New[byte]()

func ByteKeySet 

func ByteKeySet[T any](theMap map[byte]T) Byte

ByteKeySet creates a Byte from a keys of a map[byte](? extends interface{}). If the value passed in is not actually a map, this will panic.

func NewByte 

func NewByte(items ...byte) Byte

NewByte creates a Byte from a list of values.

func (Byte) Clone
