Enum arrow2::datatypes::PhysicalType

pub enum PhysicalType {
    Null,

}

The set of physical types: unique in-memory representations of an Arrow array. A physical type has a one-to-many relationship with a crate::datatypes::DataType and a one-to-one mapping to each struct in this crate that implements crate::array::Array.

Variants

Null

A Null with no allocation.

Boolean

A boolean represented as a single bit.

Primitive(PrimitiveType)

An array where each slot has a known compile-time size.

Binary

Opaque binary data of variable length.

FixedSizeBinary

Opaque binary data of fixed size.

LargeBinary

Opaque binary data of variable length and 64-bit offsets.

Utf8

A variable-length string in Unicode with UTF-8 encoding.

LargeUtf8

A variable-length string in Unicode with UFT-8 encoding and 64-bit offsets.

List

A list of some data type with variable length.

FixedSizeList

A list of some data type with fixed length.

LargeList

A list of some data type with variable length and 64-bit offsets.

Struct

A nested type that contains an arbitrary number of fields.

Union

A nested type that represents slots of differing types.

Map

A nested type.

Dictionary(IntegerType)

A dictionary encoded array by IntegerType.

Implementations

impl PhysicalType

pub fn eq_primitive(&self, primitive: PrimitiveType) -> bool

Whether this physical type equals PhysicalType::Primitive of type primitive.

Trait Implementations

impl Clone for PhysicalType

fn clone(&self) -> PhysicalType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PhysicalType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for PhysicalType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PhysicalType

fn eq(&self, other: &PhysicalType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
