Struct PresentationState 

pub struct PresentationState { /* private fields */ }

Combines the control-ownership state machine with the current tab list, bumping a monotonic revision on every actual change — never on a no-op event or a re-set of identical tabs — so a subscriber never mistakes “I asked” for “it changed.”

Implementations

impl PresentationState

pub fn new() -> Self

pub fn control(&self) -> &ControlState

pub fn apply_control(&mut self, event: ControlEvent) -> Vec<ControlEffect>

Apply one control-ownership event. Bumps revision iff the control state actually changed as a result.

pub fn set_tabs(&mut self, tabs: Vec<TabInfo>)

Replace the tab list — fed from ChromiumBackend::list_tabs() (or a future subscribe_tabs() update). Bumps revision iff it actually changed.

pub fn snapshot(&self) -> Presentation

The current snapshot. Cheap to call repeatedly — only apply_control/set_tabs advance revision, not this.
