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 child was reaped with a zero exit status and no I/O error.

Failed(String)

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