Module binding 

Interactive state binding for reactive UI.

This module provides mechanisms to bind UI widget properties to application state, enabling declarative data flow and automatic UI updates.

Binding Types

• Binding<T> - Two-way binding for read/write access
• Derived<T> - Read-only computed value from state
• PropertyPath - Path to a property in state (e.g., “user.name”)

Example

use presentar_core::binding::{Binding, Derived, PropertyPath};

// Create a binding to state.count
let count_binding = Binding::new(|| state.count, |v| state.count = v);

// Create a derived value
let doubled = Derived::new(|| state.count * 2);
