Core runtime for the Tork web framework.
This crate holds everything that runs at request time: the HTTP server built
on Hyper and Tokio, the router, the dependency-injection traits, response and
error types. It contains no procedural macros; those live in tork-macros.
End users do not depend on this crate directly. They depend on the tork
facade crate, which re-exports the public surface defined here.
