Trait OutboxSender 

Source 
pub trait OutboxSender: Send + Sync {
    // Required method
    fn send<'life0, 'life1, 'async_trait>(
        &'life0 self,
        entry: &'life1 OutboxEntry,
    ) -> Pin<Box<dyn Future<Output = Dispatched> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}
Expand description

Calls the external system for one outbox row.

The implementation owns the transport and the credentials; this module owns the bookkeeping. Two obligations are the application’s:

  • forward OutboxEntry::idempotency_key to the remote, in whatever header or field it deduplicates on. It is the same key the command was admitted under, so a row dispatched twice after a crash is one effect;
  • classify honestly. A transport error after the bytes were written is Dispatched::Unknown, not Dispatched::Retryable. If you cannot tell the two apart, it is Unknown.

Required Methods§

Source

fn send<'life0, 'life1, 'async_trait>( &'life0 self, entry: &'life1 OutboxEntry, ) -> Pin<Box<dyn Future<Output = Dispatched> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Sends one row.

Dyn Compatibility§

This trait is dyn compatible.

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