Apollo Framework

The Apollo framework is essentailly a runtime and a toolkit for building stable and robust server software.

Apollo was extracted out of Jupiter to make its core parts usable by other libraries or applications.

Apollo provides a small dependency injection helper called Platform along with some tooling to setup logging, format messages and to react on signals. This is commonly required to properly run inside a Docker container.

Most notably a Config and a Server component is provided, both fully aync as they built up on Tokio.

The Config monitors a local config file and broadcasts a change event throughout the whole platform once a new configuration is available.

The Server opens a port and spins of a loop which accepts and handles connections. The protocol implementation to be applied to each connection can be passed in using a closure or function reference.

Note that the server also monitors the config and will re-allocate a new port if the underlying config changes. This permits for zero downtime migrations during releases.
