Functions ¶

func Bools ¶

func Bools(v ...int) []bool

func FPUnwind ¶

func FPUnwind()

FPUnwind does frame pointer unwinding. It is implemented in assembly. If frame pointers are broken, it will crash. It is currently only implemented for arm64

func GetDataType ¶

func GetDataType[T constraints.Integer | constraints.Float | bool | string | []byte | float16.Num]() arrow.DataType

func IntsToBitsLSB ¶

func IntsToBitsLSB(v ...int32) []byte

IntsToBitsLSB encodes ints as LSB 0 bit numbering per https://en.wikipedia.org/wiki/Bit_numbering#LSB_0_bit_numbering The low bit of each nibble is tested, therefore integers should be written as 8-digit hex numbers consisting of 1s or 0s.

IntsToBitsLSB(0x11001010) -> 0x35
