    fn on_page_finished(&self);
    fn handle_post_message(&self, msg: String);

WebView delegate trait - focused on WebView events only

Required Methods

fn on_page_started(&self)

Called when the page starts loading

fn on_page_finished(&self)

Called when the page finishes loading

fn handle_post_message(&self, msg: String)

Handles a postMessage from the page View(WebView)

fn log(&self, level: LogLevel, message: &str)

Receive log from WebView

Provided Methods

fn on_load_error(&self, _error: &LoadError)

Called when a main-frame page load fails (e.g. DNS failure, network unreachable, TLS error).

Only fires for the main document; sub-resource errors are ignored. Default is a no-op so existing implementations do not need to change.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
