Struct WindowIpc

pub struct WindowIpc { /* private fields */ }

The Window’s IPC interface, used for evalling, events, etc.

Implementations

impl WindowIpc

pub fn new(ipc: Arc<Mutex<Option<BrowserIpc>>>) -> Self

pub fn block_until_initialized(&self) -> Result<(), CrowserError>

Wait until the IPC layer has made a connection with the window.
