-- import "vimagination.zapto.org/bitmask"
Package bitmask implements a simple bitmask type.
Usage
type BitMask
type BitMask []byte
BitMask is the main type. It is completely safe to cast from an existing byte slice or to create a BitMask with make.
func New
func New(bits int) BitMask
New creates a new BitMask with enough storage to hold at least the required number of bits.
func (BitMask) Get
func (b BitMask) Get(bit int) bool
Get will retrieve the bool stored at given bit position.
func (BitMask) Set
func (b BitMask) Set(bit int, d bool)
Set will set the given bool at the given position.
func (BitMask) SetIfNot
func (b BitMask) SetIfNot(bit int, d bool) bool
SetIfNot will set the given bool at the given position and return true if the value has changed.
