Struct HandlerContext 

pub struct HandlerContext {
    pub app_handle: Arc<dyn Any + Send + Sync>,
    pub webview_label: Option<String>,
}

Context passed from the plugin to #[command] handlers.

Wraps the application handle (as Arc<dyn Any>) and optionally the webview label of the requesting window. The #[command] macro generates code that downcasts the app handle to extract State<T>, AppHandle, Window, or WebviewWindow parameters.

Plugin authors construct this in the protocol handler; end users never interact with it directly.

Fields

app_handle: Arc<dyn Any + Send + Sync>

The AppHandle<Wry> (or equivalent), type-erased.

webview_label: Option<String>

Label of the webview that originated the request, if known.

Implementations

impl HandlerContext

pub fn new( app_handle: Arc<dyn Any + Send + Sync>, webview_label: Option<String>, ) -> Self
