Enum SessionExitStatus 

pub enum SessionExitStatus {
    Running,
    Completed,
    Failed(String),
}

Liveness state of a DuplexSession’s background task.

Surfaced through DuplexSession::is_alive, DuplexSession::exit_status, and DuplexSession::wait_for_exit for service-shaped hosts that want non-consuming visibility into whether a session is still usable. The closing DuplexSession::close still returns the full Result for the one caller that consumes the session.

Failed carries a String rather than the full Error because the underlying watch channel requires Clone and Error is not Clone (its Io variant wraps a non-Clone std::io::Error). The full error remains available via DuplexSession::close.

Variants

Running

The session task is still running.

Completed

The session task completed normally (close, stdout EOF without error).

Failed(String)

The session task ended with an error. Carries the error’s Display rendering.
