AlignDown rounds a length down to an alignment.

AlignUp rounds a length up to an alignment.

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

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

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

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

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

IsPowerOfTwo returns true if v is power of 2.

IsPowerOfTwo returns true if v is power of 2.

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

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

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

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

MostSignificantOne64 returns the index of the most significant 1 bit in x.

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.
