19/// BoxConditionalBiMutatingFunction struct
20///
21/// A conditional bi-mutating-function that only executes when a bi-predicate is
22/// satisfied. Uses `BoxBiMutatingFunction` and `BoxBiPredicate` for single
23/// ownership semantics.
24///
25/// This type is typically created by calling `BoxBiMutatingFunction::when()` and is
26/// designed to work with the `or_else()` method to create if-then-else logic.
27///
28/// # Features
29///
30/// - **Single Ownership**: Not cloneable, ownership moves on use
31/// - **Conditional Execution**: Only computes when bi-predicate returns `true`
32/// - **Chainable**: Can add `or_else` branch to create if-then-else logic
33/// - **Implements BiMutatingFunction**: Can be used anywhere a `BiMutatingFunction` is expected
