## Dependency diagram of the project

```mermaid

    lavina-->mgmt-api;
    lavina-->projection-irc;
    lavina-->projection-xmpp;
    lavina-->lavina-core;

    projection-irc-->proto-irc;

    projection-xmpp-->proto-xmpp;
    projection-xmpp-->lavina-core;

    sim-irc-->proto-irc;

    sim-xmpp-->proto-xmpp;
    sim-xmpp-->mgmt-api;

    workspace-->lavina;
    workspace-->sim-irc;
    workspace-->sim-xmpp;
```

A few rules:
- Only projections should be direct deps of `lavina`, there is no need to depend on `proto-*` crates.
- On the other hand, projections should not be dependencies of `sim-*` crates.
- `lavina-core` does not depend on protocol-specific crates.
