Functions

func Bswap32

func Bswap32(x uint32) uint32

Bswap32 returns its input with byte order reversed 0x01020304 -> 0x04030201

func Bswap64

func Bswap64(x uint64) uint64

Bswap64 returns its input with byte order reversed 0x0102030405060708 -> 0x0807060504030201

func Ctz32

func Ctz32(x uint32) uint32

Ctz32 counts trailing (low-order) zeroes, and if all are zero, then 32.

func Ctz64

func Ctz64(x uint64) uint64

Ctz64 counts trailing (low-order) zeroes, and if all are zero, then 64.
