Functions ¶

func AlignDown ¶

func AlignDown(length int, align uint) int

AlignDown rounds a length down to an alignment. align must be a power of 2.

func AlignUp ¶

func AlignUp(length int, align uint) int

AlignUp rounds a length up to an alignment. align must be a power of 2.

func ForEachSetBit64 ¶

func ForEachSetBit64(x uint64, f func(i int))

ForEachSetBit64 calls f once for each set bit in x, with argument i equal to the set bit's index.

func IsAnyOn ¶

func IsAnyOn(mask, bits T) bool

IsAnyOn returns true if *any* bit set in 'bits' is set in 'mask'.

func IsOn ¶

func IsOn(mask, bits T) bool

IsOn returns true if *all* bits set in 'bits' are set in 'mask'.

func IsPowerOfTwo ¶

func IsPowerOfTwo(v T) bool

IsPowerOfTwo returns true if v is power of 2.

func MostSignificantOne64 ¶

func MostSignificantOne64(x uint64) int

MostSignificantOne64 returns the index of the most significant 1 bit in x. If x is 0, MostSignificantOne64 returns 64.

func TrailingZeros64 ¶

func TrailingZeros64(x uint64) int

TrailingZeros64 returns the number of bits before the least significant 1 bit in x; in other words, it returns the index of the least significant 1 bit in x. If x is 0, TrailingZeros64 returns 64.

Types ¶

type T ¶

type T uint64

T is a required type parameter that must be an integral type.

func Mask ¶

func Mask(is ...int) T

Mask returns a T with all of the given bits set.

func MaskOf ¶

func MaskOf(i int) T

MaskOf is like Mask, but sets only a single bit (more efficiently).
