Struct NavigationProgress 

pub struct NavigationProgress { /* private fields */ }

Attempt bookkeeping every consumer otherwise re-implements: because attempts may overlap (WebView2), a terminal event for an older attempt must not clear loading UI for the newest one.

Implementations

impl NavigationProgress

pub fn apply(&mut self, event: &NavigationEvent)

Fold one event into the progress state.

pub fn is_loading(&self) -> bool

True while the newest attempt has no terminal event.

pub fn current(&self) -> Option<NavigationId>

The newest attempt, until its terminal arrives.

pub fn is_current(&self, id: NavigationId) -> bool

Whether id is the newest attempt (terminal or not).

pub fn classify<'a>( &mut self, event: &'a NavigationEvent, ) -> NavigationOutcome<'a>

Folds event in and classifies it for a delegate that only acts on the newest attempt. Every consumer needs the same rule — a stale terminal must never mark a newer load as loaded or failed — so it lives here rather than being re-derived per delegate.
