into_value ( self ) → Option<T> method [source] ¶ method [source] ¶ into_value

Take the value the operation produced before cleanup failed.

None unless the operation succeeded, which is the one case where a result would otherwise be lost: the outer Result is Err either way.

Examples

// The work is done even when tearing the session down failed, so the
// value is worth keeping rather than discarding with the error.
let outcome = server
    .with_session("build", async |session| {
        Ok::<_, libtmux::Error>(session.id().to_string())
    })
    .await;

let id = match outcome {
    Ok(id) => Some(id),
    Err(error) => error.into_value(),
};
