Trait IEventHandler 

pub trait IEventHandler<T>: Send + Sync
where
    T: IEventRequest,
{
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        event: T,
    ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
       where 'life0: 'async_trait,
             Self: 'async_trait;
}

Handles a single IEventRequest, performing side effects.

#[async_trait]
impl IEventHandler<UserCreatedEvent> for SendWelcomeEmailHandler {
    async fn handle(&self, event: UserCreatedEvent) -> Result<()> { ... }
}

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, event: T, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
