Module arrow2::types

This module contains traits to handle all physical types used in this crate. Most physical types used in this crate are native Rust types, like i32. The most important trait is NativeType, implemented for all Arrow types with a Rust correspondence (such as i32 or f64).

Another important trait is BitChunk, describing types that can be used to represent chunks of bits (e.g. u8, u16), and BitChunkIter, that can be used to iterate over bitmaps in BitChunks. Finally, this module also contains traits used to compile code optimized for SIMD instructions at [simd].

Modules

simd

Structs

BitChunkIter

An iterator of bool over a BitChunk. This iterator is often compiled to SIMD instructions. The LSB corresponds to the first slot, as defined by the arrow specification.

days_ms

The in-memory representation of the DayMillisecond variant of arrow’s “Interval” logical type.

Traits

BitChunk

Something that can be use as a chunk of bits. This is used to create masks of a given number of lengths, whose width is 1. In simd_packed notation, this corresponds to m1xY.

NativeType

Trait declaring any type that can be allocated, serialized and deserialized by this crate. All data-heavy memory operations are implemented for this trait alone.

NaturalDataType

Trait denoting anything that has a natural logical DataType. For example, DataType::Int32 for i32.
