Implementations

impl<A, T> FutureLoader<A, T>

where A: 'static, T: 'static,

pub fn new_state( ctx: &mut EventCtx<'_>, future: Pin<Box<dyn Send + Future<Output = Result<Box<dyn Send + FnOnce(&A) -> T>>>>>, outer_progress_receiver: Receiver<String>, inner_progress_receiver: Receiver<String>, loading_title: &str, on_load: Box<dyn FnOnce(&mut EventCtx<'_>, &mut A, Result<T>) -> Transition<A>> ) -> Box<dyn State<A>>

Trait Implementations

impl<A, T> State<A> for FutureLoader<A, T>

where A: 'static, T: 'static,

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

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

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

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.
