+ + let scoped_event = ScopedEvent { + topic: topic_owned.clone(), + scope, + event: event.clone(), + }; + + self.emit(&scoped_topic, scoped_event); + } +} + +// ... existing code ... +``` + +Il faut également exporter `ScopedEvent` : + +event_bus/src/lib.rs +```rust +// ... existing code ... + +mod bus; + +pub use bus::{ + AnyEvent, + EventBus, + Scope, + ScopeValue, + ScopedEvent, +}; + +// ... existing code ... +``` + +Tu pourras ensuite t’abonner à un événement scoped comme ceci : + +```rust +use event_bus::{EventBus, Scope, ScopeValue, ScopedEvent}; + +let topic = "channel:123:message_created"; + +event_bus.on::, _, _>(topic, |payload| async move { + println!("Topic initial : {}", payload.topic); + println!("Scope : {:?}", payload.scope); + println!("Message : {:?}", payload.event); +}); +``` + +Pour éviter de devoir reconstruire manuellement les topics, tu peux aussi ajouter une méthode utilitaire à `Scope` : + +event_bus/src/bus.rs +```rust +// ... existing code ... + +impl Scope { + pub fn topic(&self, topic: &str) -> String { + format!( + "{}:{}:{}", + self.key, + self.value.clone().into_string(), + topic + ) + } +} + +impl IntoIterator for Scope { + type Item = Scope; + type IntoIter = iter::Once; + + fn into_iter(self) -> Self::IntoIter { + iter::once(self) + } +} + +// ... existing code ... +``` + +Et `emit_scoped` devient plus lisible : + +```rust +for scope in scopes { + let scoped_topic = scope.topic(topic); + + let scoped_event = ScopedEvent { + topic: topic.to_string(), + scope, + event: event.clone(), + }; + + self.emit(&scoped_topic, scoped_event); +} +``` + +### Variante recommandée + +Si tu veux que **tous les abonnés**, y compris ceux du topic général, reçoivent toujours la même structure, il vaut mieux envelopper également l’événement général : + +```rust +pub struct EventEnvelope { + pub topic: String, + pub scope: Option, + pub event: T, +} +``` + +Dans ce cas : + +- événement général : `scope: None` ;

Le bus devrait rester **générique** et ne pas connaître la structure métier des événements. Les événements peuvent vivre dans le projet principal, par exemple : + +```text +src/ +├── events/ +│ ├── mod.rs +│ ├── message.rs +│ ├── channel.rs +│ ├── permission.rs +│ └── server.rs +``` + +Ou, si tu préfères le vocabulaire métier : + +```text +src/ +├── domain/ +│ └── events/ +│ ├── mod.rs +│ ├── message.rs +│ ├── channel.rs +│ └── permission.rs +``` + +Je choisirais plutôt `events/`, car ce dossier représente clairement les événements publiés dans l’application. + +### Exemple + +src/events/message.rs +```rust +use uuid::Uuid; + +#[derive(Debug, Clone)] +pub struct MessageCreated { + pub message_id: Uuid, + pub channel_id: Uuid, + pub user_id: Uuid, +} + +#[derive(Debug, Clone)] +pub struct MessageUpdated { + pub message_id: Uuid, + pub channel_id: Uuid, +} + +#[derive(Debug, Clone)] +pub struct MessageDeleted { + pub message_id: Uuid, + pub channel_id: Uuid, +} +``` + +src/events/channel.rs +```rust +use uuid::Uuid; + +#[derive(Debug, Clone)] +pub struct ChannelCreated { + pub channel_id: Uuid, + pub server_id: Uuid, +} + +#[derive(Debug, Clone)] +pub struct ChannelUpdated { + pub channel_id: Uuid, + pub server_id: Uuid, +} + +#[derive(Debug, Clone)] +pub struct ChannelDeleted { + pub channel_id: Uuid, + pub server_id: Uuid, +} +``` + +Puis tu centralises les exports : + +src/events/mod.rs +```rust +pub mod channel; +pub mod message; +pub mod permission; +pub mod server; + +pub use channel::{ + ChannelCreated, + ChannelDeleted, + ChannelUpdated, +}; + +pub use message::{ + MessageCreated, + MessageDeleted, + MessageUpdated, +}; +``` + +Et dans `src/lib.rs` : + +src/lib.rs +```rust +// ... existing code ... + +pub mod events; + +// ... existing code ... +``` + +L’émission devient explicite et typée : + +```rust +use crate::events::message::MessageCreated; + +state.event_bus.emit( + "message_created", + MessageCreated { + message_id: message.id, + channel_id: message.channel_id, + user_id: message.user_id, + }, +); +``` + +Pour les scopes, tu peux garder le système actuel du bus et simplement utiliser les données présentes dans l’événement : + +```rust +use event_bus::{Scope, ScopeValue}; +use crate::events::message::MessageCreated; + +let event = MessageCreated { + message_id: message.id, + channel_id: message.channel_id, + user_id: message.user_id, +}; + +state.event_bus.emit_scoped( + "message_created", + [ + Scope { + key: "channel".to_string(), + value: ScopeValue::Uuid(event.channel_id), + }, + Scope { + key: "user".to_string(), + value: ScopeValue::Uuid(event.user_id), + }, + ], + event, +); +``` + +L’intérêt est que : + +- le bus ne connaît aucun événement métier ; +- chaque événement possède son propre contrat ; +- les abonnés reçoivent directement un type précis ; +- les événements sont facilement réutilisables par les services, le gateway et la synchronisation des permissions ; +- tu évites une grosse enum centrale qui deviendrait rapidement difficile à maintenir. + +Je mettrais uniquement dans `event_bus` les primitives génériques comme `EventBus`, `Scope` et `ScopeValue`. Les structs concrètes comme `MessageCreated`, `ChannelDeleted` ou `ServerUserUpdated` doivent rester dans le crate applicatif. + +kotlin.Unit +
