Module polars::datatypes [−][src]
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.
Structs
Maps a logical type to a a chunked array implementation of the physical type. This saves a lot of compiler bloat and allows us to reuse functionality.
Enums
The set of supported logical types.
Each variant uniquely identifies a logical type, which define specific semantics to the data (e.g. how it should be represented).
Each variant has a corresponding [PhysicalType
], obtained via DataType::to_physical_type
,
which declares the in-memory representation of data.
The DataType::Extension
is special in that it augments a DataType
with metadata to support custom types.
Use to_logical_type
to desugar such type and return its correspoding logical type.
The time units defined in Arrow.
Traits
Any type that is not nested
