19/// Type alias for `BoxBiFunction<T, T, R>`
20///
21/// Represents a binary function that takes two values of type `T` and produces
22/// a value of type `R`, with single ownership semantics. Similar to Java's
23/// `BiFunction<T, T, R>` but with different type parameters.
24///
25/// # Examples
26///
27/// ```rust
28/// use qubit_function::{BoxBinaryFunction, BiFunction};
29///
30/// let add: BoxBinaryFunction<i32, i32> = BoxBinaryFunction::new(|x, y| *x + *y);
31/// assert_eq!(add.apply(&20, &22), 42);
32/// ```
