Module polars_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 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.

Modules

• aggregatecompute_aggregate
  Contains different aggregation functions
• arity
  Defines kernels suitable to perform operations to primitive arrays.
• arity_assign
  Defines generics suitable to perform operations to PrimitiveArray in-place.
• bitwisecompute_bitwise
  Contains bitwise operators: or, and, xor and not.
• booleancompute_boolean
  null-preserving operators such as and, or and not.
• boolean_kleenecompute_boolean_kleene
  Boolean operators of Kleene logic.
• castcompute_cast
  Defines different casting operators such as cast or [primitive_to_binary].
• concatenate
  Example:
• takecompute_take
  Defines take kernel for Array
• temporalcompute_temporal
  Defines temporal kernels for time and date related functions.
