Data Types

Logical data types for Vortex arrays. DType represents a logical type, and PType enumerates the physical primitive types.

PType

enum class vortex::PType : uint8_t

Values:

enumerator U8

enumerator U16

enumerator U32

enumerator U64

enumerator I8

enumerator I16

enumerator I32

enumerator I64

enumerator F16

enumerator F32

enumerator F64

DType

namespace dtype

Functions

DType null()

DType bool_(bool nullable = false)

DType primitive(PType ptype, bool nullable = false)

DType int8(bool nullable = false)

DType int16(bool nullable = false)

DType int32(bool nullable = false)

DType int64(bool nullable = false)

DType uint8(bool nullable = false)

DType uint16(bool nullable = false)

DType uint32(bool nullable = false)

DType uint64(bool nullable = false)

DType float16(bool nullable = false)

DType float32(bool nullable = false)

DType float64(bool nullable = false)

DType decimal(uint8_t precision = 10, int8_t scale = 0, bool nullable = false)

DType utf8(bool nullable = false)

DType binary(bool nullable = false)

DType from_arrow(struct ArrowSchema &schema, bool non_nullable = false)

TODO: Other DTypes are only supported by creating from Arrow for now.
