impl Middleware for TracingMiddleware

fn before<'life0, 'life1, 'async_trait>( &'life0 self, message: &'life1 TaskMessage, ) -> Pin<Box<dyn Future<Output = Result<(), KojinError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Called before task execution. Return Err to abort.

fn after<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, message: &'life1 TaskMessage, _result: &'life2 Value, ) -> Pin<Box<dyn Future<Output = Result<(), KojinError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called after successful task execution.

fn on_error<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, message: &'life1 TaskMessage, error: &'life2 KojinError, ) -> Pin<Box<dyn Future<Output = Result<(), KojinError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called when task execution fails.
