Module polars::export::arrow::compute

contains a wide range of compute operations (e.g. arithmetics, aggregate, filter, comparison, and [sort])

This module’s general design is that each operator has two interfaces, a statically-typed version and a dynamically-typed version. The statically-typed version expects concrete arrays (such as PrimitiveArray); the dynamically-typed version expects &dyn Array and errors if the the type is not supported. Some dynamically-typed operators have an auxiliary function, can_*, that returns true if the operator can be applied to the particular DataType.
