Module arrow2::compute

Contains operators over arrays. 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 (like 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.
