Enum ScreenOutcome 

pub enum ScreenOutcome {
    ReturnToParent,
    QuitAll,
    Continue,
}

What a nested screen’s event loop did, for its caller to interpret. A screen that owns its own sub-context (e.g. TeleopUi) should never mutate the outer loop’s shutdown flag directly - it reports what happened here, and lets the caller (which knows how it was entered) decide what that means. See ops/teleop.rs::enter_teleop_mode, which interprets ReturnToParent differently depending on whether it was entered via 's' (simulation hand-off, so backing out means “stop the simulation and return to the dev-mode menu”) or 't' (standalone teleop, so backing out just closes the screen).

Variants

ReturnToParent

TerminationIntent::StopCurrent fired, or the screen’s own back-out (e.g. q/Esc) completed normally.

QuitAll

TerminationIntent::QuitAll fired - propagate outward unswallowed, all the way to the top-level running flag, so the outer loop’s own if !running.load() { break } handles full session teardown.

Continue

Nothing terminal happened; keep running the screen’s event loop.
