3/// Base trait for all interceptors in Sword.
4/// Implement this trait to create interceptors that can be automatically
5/// registered and built via the dependency injection system.
6///
7/// This means that the interceptor can have dependencies injected into it,
8/// and also be stored one time and reused  throughout the application lifecycle.
