Crate vortex_dtype

A type system for Vortex

This crate contains the core logical type system for Vortex, including the definition of data types, and (optionally) logic for their serialization and deserialization.

Re-exports

• pub use half;

Modules

• field
  Selectors for fields in (possibly nested) StructDTypes
• flatbuffers
  Flatbuffer representations for DTypes
• proto
  Protocol buffer representations for DTypes

Macros

• match_each_float_ptype
  Macro to match over each floating point type, binding the corresponding native type (from NativePType)
• match_each_integer_ptype
  Macro to match over each integer PType, binding the corresponding native type (from NativePType)
• match_each_native_ptype
  Macro to match over each PType, binding the corresponding native type (from NativePType)
• match_each_unsigned_integer_ptype
  Macro to match over each unsigned integer type, binding the corresponding native type (from NativePType)

Structs

• ExtDType
  A type descriptor for an extension type
• ExtID
  A unique identifier for an extension type
• ExtMetadata
  Opaque metadata for an extension type
• FieldInfo
  Information about a field in a struct dtype
• StructDType
  A struct dtype is a list of names and corresponding dtypes

Enums

• DType
  The logical types of elements in Vortex arrays.
• Nullability
  Whether an instance of a DType can be `null or not
• PType
  Physical type enum, represents the in-memory physical layout but might represent a different logical type.

Traits

• NativePType
  A trait for native Rust types that correspond 1:1 to a PType
• ToBytes
  A trait for types that can be converted to a little-endian byte slice
• TryFromBytes
  A trait for types that can be converted from a little-endian byte slice

Type Aliases
