Implementations

impl Viewer

pub fn new_state(ctx: &mut EventCtx<'_>, app: &App) -> Box<dyn State<App>>

fn arrow_for(&self, app: &App, id: AgentID) -> Option<(Polygon, Color)>

fn trace_root_cause(&self, app: &App, start: AgentID) -> (GeomBatch, String)

Figure out why some agent is blocked. Draws an arrow for each hop in the dependency chain, and gives a description of the root cause.

fn find_worst_problems( &self, ctx: &EventCtx<'_>, app: &App, ) -> (GeomBatch, Widget)

Trace the root cause for everyone, find the most common sources, highlight them, and describe them.

fn simple_root_cause(&self, start: AgentID) -> DelayCause

Trait Implementations

impl State<App> for Viewer

fn event(&mut self, ctx: &mut EventCtx<'_>, app: &mut App) -> Transition<App>

Respond to a UI event, such as input or time passing.

fn draw(&self, g: &mut GfxCtx<'_>, app: &App)

Draw

fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()

fn on_destroy(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Before this state is popped or replaced, call this.

fn recreate(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Box<dyn State<A>>

Respond to Transition::Recreate by assuming state in the app has changed, but preserving the State-specific state appropriately.
