Functions

func BitfieldString

func BitfieldString[T ~uint8 | ~uint16 | ~uint32 | ~uint64](bitfield T, bitnames []string, cfg BitfieldFormat) string

func FmtStateString

func FmtStateString(st fmt.State, verb rune) string

FmtStateString returns the fmt.Printf string that produced a given fmt.State and verb.

func FormatByteArrayStringer

func FormatByteArrayStringer(
	obj interface {
		fmt.Stringer
		fmt.Formatter
	},
	objBytes []byte,
	f fmt.State, verb rune,
)

FormatByteArrayStringer is function for helping to implement fmt.Formatter for []byte or [n]byte types that have a custom string representation. Use it like:

type MyType [16]byte

func (val MyType) String() string {
    …
}

func (val MyType) Format(f fmt.State, verb rune) {
    util.FormatByteArrayStringer(val, val[:], f, verb)
}

Types

type BitfieldFormat

type BitfieldFormat uint8

const (
	HexNone BitfieldFormat = iota
	HexLower
	HexUpper
)
