Events are a way we can communciate with the Tauri frontend from the Rust backend.
We include a feature flag for Tauri, so that we can compile this code without Tauri.
To use events, we need to do the following:
1) Make sure we are using the tauri feature flag
2) Initialize the EventState with EventState::init() *before* initializing the theseus State
3) Call emit_x functions to send events to the frontend
For emit_loading() specifically, we need to inialize the loading bar with init_loading() first and pass the received loader in
For example:
pub async fn loading_function() -> crate::Result<()> {
loading_function()).await;
}
pub async fn loading_function() -> crate::Result<()> {
let loading_bar = init_loading(LoadingBarType::StateInit, 100.0, "Loading something long...").await;

callback is a function that takes a single argument, which is the payload object (whatever Rust is trying to deliver)
You can call these to await any kind of emitted signal from Rust, and then do something with the payload object
An example place to put this is at the start of main.js before the state is initialized- that way
you can listen for any emitted signal from Rust and do something with it as the state is being initialized
Example:
import { loading_listener } from '@/helpers/events'
await loading_listener((event) => {
// event.event is the event name (useful if you want to use a single callback fn for multiple event types)
// event.payload is the payload object
console.log(event)
