§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§
Structs§
- Binary
Offset Type - Binary
Type - Boolean
Type - Categorical8
Type - Categorical16
Type - Categorical32
Type - Categorical
Mapping - Categorical
Type - Categories
- A (named) object which is used to indicate which categorical data types have the same mapping.
- Compat
Level - Date
Type - Datetime
Type - Decimal
Type - Dimension
- Duration
Type - FalseT
- Field
- Characterizes the name and the
DataTypeof a column. - Fixed
Size List Type - Float32
Type - Float64
Type - Frozen
Categories - An ordered collection of unique strings with an associated pre-computed mapping to go from string <-> index.
- Int8
Type - Int16
Type - Int32
Type - Int64
Type - Int128
Type - List
Type - 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.
- Object
Type - Owned
Object - PlSmall
Str - String type that inlines small strings.
