## Dependency diagram of the project
```mermaid
graph TD;
lavina-->mgmt-api;
lavina-->projection-irc;
lavina-->projection-xmpp;
lavina-->lavina-core;
projection-irc-->proto-irc;
projection-irc-->lavina-core;
projection-xmpp-->proto-xmpp;
projection-xmpp-->lavina-core;

sim-irc-->mgmt-api;
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.
