Function device_watcher::recursive_wait_and_open

pub async fn recursive_wait_and_open<P: ProtocolMarker>(
    dir: &DirectoryProxy,
    name: &str
) -> Result<P::Proxy>

Open the path name within dir. This function waits for each directory to be available before it opens it. If the path never appears this function will wait forever. Does NOT support fio::DirectoryMarker. Use recursive_wait_and_open_directory() instead. TODO(https://fxbug.dev/42072966): Specialize this function to support fio::DirectoryMarker
