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.
