Types

type ConvertedType

type ConvertedType int32

DEPRECATED: Common types used by frameworks(e.g. hive, pig) using parquet. ConvertedType is superseded by LogicalType. This enum should not be extended.

See LogicalTypes.md for conversion between ConvertedType and LogicalType.

)

type Int96

type Int96 [3]uint32

Int96 is an implementation of the deprecated INT96 parquet type.

func BytesToInt96

func BytesToInt96(data []byte) []Int96

BytesToInt96 converts the byte slice passed as argument to a slice of Int96 sharing the same backing array.

When the number of bytes in the input is not a multiple of 12, the function truncates it in the returned slice.

func Int32ToInt96

func Int32ToInt96(value int32) (i96 Int96)

Int32ToInt96 converts a int32 value to a Int96.

func Int64ToInt96

func Int64ToInt96(value int64) (i96 Int96)

Int64ToInt96 converts a int64 value to Int96.

func MaxInt96

func MaxInt96(data []Int96) (max Int96)

func MinInt96

func MinInt96(data []Int96) (min Int96)

func MinMaxInt96

func MinMaxInt96(data []Int96) (min, max Int96)

func (Int96) Int

func (i Int96) Int() *big.Int

Int converts i to a big.Int representation.

func (Int96) Int32

func (i Int96) Int32() int32

Int32 converts i to a int32, potentially truncating the value.

func (Int96) Int64

func (i Int96) Int64() int64

Int64 converts i to a int64, potentially truncating the value.

func (Int96) IsZero

func (i Int96) IsZero() bool

IsZero returns true if i is the zero-value.

func (Int96) Len

func (i Int96) Len() int

Len returns the minimum length in bits required to store the value of i.

func (Int96) Less

func (i Int96) Less(j Int96) bool

Less returns true if i < j.

The method implements a signed comparison between the two operands.

func (Int96) Negative

func (i Int96) Negative() bool

Negative returns true if i is a negative value.

func (Int96) String

func (i Int96) String() string

String returns a string representation of i.
