lib.rs:
A framework for writing system services
About
Every application which runs as a service should implement things like logging, signal handling, graceful shutdown, CLI option parsing, and configuration file parsing. This package provides a semi-opinionated framework for doing so.
Usage
There are several traits exported here including Application, Config,
Options, and LogOptions. The two options traits should be implemented
for your CLI option loadind, Config for your config file loading, and
Application for your application logic.
The primary run method is Application::run_once which is called over and
over again in a loop. It is provided a Context type which gives the
application control of when it checks for signals. Any received signals are
passed to Application::received_signal for handling.
Once Application::run_once returns Stopping::Yes, the main loop
terminates and invokes Application::shutdown before exitting.
