| 9 | //! Composable first-order predicate trait. |
| 10 | //! |
| 11 | //! This library implements an interface to "predicates" - boolean-valued |
| 12 | //! functions of one argument. This allows combinatorial logic to be created and |
| 13 | //! assembled at runtime and then used one or more times for evaluating values. |
| 14 | //! This sort of object is really useful when creating filters and checks that |
| 15 | //! can be changed at runtime with user interaction - it allows a clean |
| 16 | //! separation of concerns where the configuration code can be used to build up |
| 17 | //! a predicate, and then that predicate can be given to the code that does the |
| 18 | //! actual filtering without the filtering code knowing anything about user |
| 19 | //! configuration. See the examples for how this can work. |
