Trait OperationOutcomeObserver 

pub trait OperationOutcomeObserver:
    Debug
    + Send
    + Sync {
    // Required method
    fn on_outcome(&self, kind: TaskKind, outcome: OperationOutcome);
}

Observes task outcomes after future destruction.

Callbacks must be short, nonblocking and panic-free, including during panic unwinding. They must not flush exporters or retain request data.

Records one terminal task outcome using bounded labels.

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