UseFunction is an alternative approach to function dispatching vis-a-vis UseMethod. It is designed for people interested in writing functional programs in R as opposed to object-oriented programs.
The '%when%' operator defines the conditions for execution for the given function. To use a function within futile.paradigm, a guard must be defined for each child function, even if it's a default guard using TRUE. Each '%when%' clause indicates a new function variant for a given function.
Provides dispatching implementations suitable for functional programming paradigms. The framework provides a mechanism for attaching guards to functions similar to Erlang, while also providing the safety of assertions reminiscent of Eiffel.
The 'ensure' function defines the conditions for successful execution for the given function. This is an optional declaration that requires a previous guard declaration for the given function.
Provides a high-level API for abstracting CRUD operations for arbitrary objects. Currently only create is provided, as this is essential for type management within futile.paradigm. Others will be added as necessary.
