/// A singly owned binary function with matching input types.
///
/// Represents a binary function that takes two values of type `T` and produces
/// a value of type `R`, with single ownership semantics. Similar to Java's
/// `BiFunction<T, T, R>` but with different type parameters.
///
/// # Examples
///
/// ```rust
/// use qubit_function::{BoxBinaryFunction, BiFunction};
///
/// let add: BoxBinaryFunction<i32, i32> = BoxBinaryFunction::new(|x: &i32, y: &i32| *x + *y);
/// assert_eq!(add.apply(&20, &22), 42);
/// ```
