Module stateful_predicate 

StatefulPredicate Abstraction

Provides predicate wrappers for closures that implement FnMut(&T) -> bool. A stateful predicate can update its own internal state while testing borrowed input values.

Use Predicate for immutable Fn(&T) -> bool predicates and StatefulPredicate when the predicate needs native FnMut semantics, such as counters, rolling windows, sampling, or stateful filters.

Structs

ArcStatefulPredicate

An Arc-based stateful predicate with thread-safe shared ownership.

BoxStatefulPredicate

A Box-based stateful predicate with single ownership.

RcStatefulPredicate

An Rc-based stateful predicate with single-threaded shared ownership.

Traits

FnStatefulPredicateOps

Extension trait providing logical composition methods for stateful closures.

StatefulPredicate

A stateful predicate trait for testing values with mutable internal state.
