Module datatypes

Expand description

§Data types supported by Polars.

At the moment Polars doesn’t include all data types available by Arrow. The goal is to incrementally support more data types and prioritize these by usability.

See the AnyValue variants for the data types that are currently supported.

Modules§

categorical
enum_
time_unit
time_zone

Structs§

BinaryOffsetType
BinaryType
BooleanType
CatIter
CategoricalChunked
CategoricalChunkedBuilder
CategoricalMapping
CategoricalType
Categories: A (named) object which is used to indicate which categorical data types have the same mapping. The underlying mapping is dynamic, and if gc is true may be automatically cleared when the last reference to it goes away.
CompatLevel
DateType
DatetimeType
DecimalType
Dimension
DurationType
FalseT
Field: Characterizes the name and the DataType of a column.
FixedSizeListType
Float32Type
Float64Type
FrozenCategories: An ordered collection of unique strings with an associated pre-computed mapping to go from string <-> index.
GlobalRevMapMerger
Int8Type
Int16Type
Int32Type
Int64Type
Int128Type
ListType
Logical: Maps a logical type to a chunked array implementation of the physical type. This saves a lot of compiler bloat and allows us to reuse functionality.
ObjectType
OwnedObject
PlSmallStr: String type that inlines small strings.
StringType
StructType
TimeType
TimeZone
TrueT
UInt8Type
UInt16Type
UInt32Type
UInt64Type

Enums§

AnyValue
ArrowDataType: The set of supported logical types in this crate.
ArrowTimeUnit: The time units defined in Arrow.

DataType
ReshapeDimension: A dimension in a reshape.
