Module middleware 

Middleware pipeline primitives.

Structs

Next

Opaque continuation passed to a Middleware. Calling Next::run proceeds to the next middleware in the chain or to the Terminal if the chain is exhausted.

Traits

Middleware

Intercepts a dispatch before reaching its handler.

Terminal

Terminal of the middleware chain. The mediator (issue #6) supplies a concrete implementation that downcasts the message and invokes the registered handler.

Type Aliases

BoxOutput

Type-erased handler output, passed through the middleware chain.
