Trait AroundMiddleware 

pub trait AroundMiddleware {
    // Required method
    fn around(self, handler: Box<dyn Handler>) -> Box<dyn Handler>;
}

AroundMiddleware are used to wrap and replace the Handler in a Chain.

AroundMiddleware produce Handlers through their around method, which is called once on insertion into a Chain or can be called manually outside of a Chain.

Required Methods

fn around(self, handler: Box<dyn Handler>) -> Box<dyn Handler>

Produce a Handler from this AroundMiddleware given another Handler.

Usually this means wrapping the handler and editing the Request on the way in and the Response on the way out.

This is called only once, when an AroundMiddleware is added to a Chain using Chain::around, it is passed the Chain’s current Handler.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
