Functions ¶
func FormatRecoveredError ¶
FormatRecoveredError is used in cases where a panic/recover receives an object which is potentially an error that could be wrapped, instead of formatted, so that callers can see it. This may be useful, for example, with custom Allocators which panic to signal failure; these panics will be recovered as wrapped errors, letting the client distinguish them.
func GetMinMaxInt8 ¶
GetMinMaxInt8 returns the min and max for a int8 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxInt16 ¶
GetMinMaxInt16 returns the min and max for a int16 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxInt32 ¶
GetMinMaxInt32 returns the min and max for a int32 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxInt64 ¶
GetMinMaxInt64 returns the min and max for a int64 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxUint8 ¶
GetMinMaxUint8 returns the min and max for a uint8 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxUint16 ¶
GetMinMaxUint16 returns the min and max for a uint16 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxUint32 ¶
GetMinMaxUint32 returns the min and max for a uint32 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func GetMinMaxUint64 ¶
GetMinMaxUint64 returns the min and max for a uint64 slice, using AVX2 or SSE4 cpu extensions if available, falling back to a pure go implementation if they are unavailable or built with the noasm tag.
func Max ¶
func Max[T constraints.Ordered](a, b T) T
func Min ¶
func Min[T constraints.Ordered](a, b T) T
func NewBufferedReader ¶
NewBufferedReader returns a buffered reader with similar semantics to bufio.Reader except Peek will expand the internal buffer if needed rather than return an error.
func TransposeInts ¶
TransposeInts expects two integral slices and the values they map to. Returning an error if either src or dest are not an integral type.
func TransposeIntsBuffers ¶
func TransposeIntsBuffers(inType, outType arrow.DataType, indata, outdata []byte, inOffset, outOffset int, length int, transposeMap []int32) error
TransposeIntsBuffers takes the data-types, byte buffers, and offsets of a source and destination buffer to perform TransposeInts on with the provided mapping data.
