Nushell Plugin
Encoder: msgpack
Version: 0.117.0
Plugin file path: /usr/bin/nu_plugin_polars

Command: polars
Description:
 > Operate with data in a dataframe format.

Extra description:
 >
You must use one of the subcommands below. Using this command as-is will only produce this help message.

The following are the main datatypes (wrapped from Polars) that are used by these subcommands:

Lazy and Strict dataframes (called `NuLazyFrame` and `NuDataFrame` in error messages) are the main
data structure.

Expressions, representing various column operations (called `NuExpression`), are passed to many commands such as
`polars filter` or `polars with-column`. Most nushell operators are supported in these expressions, importantly
arithmetic, comparison and boolean logical.

Groupbys (`NuLazyGroupBy`), the output of a `polars group-by`, represent a grouped dataframe and are typically piped
to the `polars agg` command with some column expressions for aggregation which then returns a dataframe.
