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