OmniPaxos uses the slog crate to provide system-wide logging facilities. Logging works out of the box with a default asynchronous console and file logger implementation.
The actual logging levels are controlled via build features. The default features correspond to
release_max_level_info, that is in debug builds all levels are shown, while in the release profile only
info and more severe message are shown.
Sometimes the default logging configuration is not sufficient for a particular application. For example, you might need a larger queue size in the
Async drain, or you may want to write to a file instead of the terminal.
The user can provide a custom implementation based on slog.
