Struct eframe::web::WebRunner

pub struct WebRunner { /* private fields */ }

This is how eframe runs your wepp application

This is cheap to clone.

See the crate level docs for an example.

Implementations

impl WebRunner

pub fn new() -> Self

Will install a panic handler that will catch and log any panics

pub async fn start( &self, canvas_id: &str, web_options: WebOptions, app_creator: AppCreator ) -> Result<(), JsValue>

Create the application, install callbacks, and start running the app.

Errors

Failing to initialize graphics.

pub fn has_panicked(&self) -> bool

Has there been a panic?

pub fn panic_summary(&self) -> Option<PanicSummary>

What was the panic message and callstack?

pub fn destroy(&self)

Shut down eframe and clean up resources.

pub fn app_mut<ConcreteApp: 'static + App>( &self ) -> Option<RefMut<'_, ConcreteApp>>

Get mutable access to the concrete App we enclose.

This will panic if your app does not implement App::as_any_mut, and return None if this runner has panicked.

pub fn add_event_listener<E: JsCast>( &self, target: &EventTarget, event_name: &'static str, closure: impl FnMut(E, &mut AppRunner) + 'static ) -> Result<(), JsValue>

Convenience function to reduce boilerplate and ensure that all event handlers are dealt with in the same way.

All events added with this method will automatically be unsubscribed on panic, or when Self::destroy is called.

Trait Implementations

impl Clone for WebRunner

fn clone(&self) -> WebRunner

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
