//! Defines the `RcBinaryFunction` public type.

use super::RcBiFunction;

/// A locally shared binary function with matching input types.
///
/// Represents a single-threaded binary function that takes two values of type
/// `T` and produces a value of type `R`. Similar to Java's `BiFunction<T, T,
/// R>` with shared, single-threaded ownership.
///
/// # Examples
///
/// ```rust
/// use qubit_function::{RcBinaryFunction, BiFunction};
///
/// let max: RcBinaryFunction<i32, i32> = RcBinaryFunction::new(|x: &i32, y: &i32| if x > y { *x } else { *y });
/// let max_clone = max.clone();
/// assert_eq!(max.apply(&30, &42), 42);
/// assert_eq!(max_clone.apply(&30, &42), 42);
/// ```
