Struct ViewportProps 

pub struct ViewportProps {
    pub worker_url: String,
    pub grabbing: RwSignal<bool>,
    pub on_input: Callback<ViewportEvent>,
    pub on_connect: Callback<(Bridge, OffscreenCanvas, f32, f32)>,
    pub on_message: Callback<JsValue>,
    pub on_error: Option<Callback<String>>,
}

Props for the Viewport component.

A render surface backed by a web worker. On mount it sizes a canvas to the device pixel ratio, transfers it to an OffscreenCanvas, spawns the module worker at worker_url, and reports the Bridge, canvas, and dimensions through on_connect. It forwards pointer, wheel, touch, and resize events as ViewportEvents to on_input, worker messages to on_message, failures to the optional on_error, and toggles the grabbing signal during pointer interaction.

Required Props

• worker_url: impl Into<String>
• grabbing: RwSignal<bool>
• on_input: Callback<ViewportEvent>
• on_connect: Callback<(Bridge, OffscreenCanvas, f32, f32)>
• on_message: Callback<JsValue>

Optional Props

• on_error: Callback<String>

Fields

worker_url: String

grabbing: RwSignal<bool>

on_input: Callback<ViewportEvent>

on_connect: Callback<(Bridge, OffscreenCanvas, f32, f32)>

on_message: Callback<JsValue>

on_error: Option<Callback<String>>

Implementations

impl ViewportProps

pub fn builder() -> ViewportPropsBuilder<((), (), (), (), (), ())>

Create a builder for building ViewportProps. On the builder, call .worker_url(...), .grabbing(...), .on_input(...), .on_connect(...), .on_message(...), .on_error(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of ViewportProps.
