Attribute Macro file_ext_plugin

#[file_ext_plugin]

Use this macro to mark an impl block on a file extension plugin. This will alter the new and load methods to return a tokio::task::JoinHandle with the provided runtime. The parameter must be a function that takes an async closure and returns a JoinHandle.

static DEFAULT_TOKIO_RUNTIME: std::sync::LazyLock<tokio::runtime::Runtime> =
    std::sync::LazyLock::new(|| {
        tokio::runtime::Runtime::new().expect("Failed to create Tokio runtime")
    });

fn default_runtime<T: Send + 'static>(
    task: impl Future<Output = T> + Send + 'static,
) -> tokio::task::JoinHandle<T> {
    match tokio::runtime::Handle::try_current() {
        Ok(handle) => handle.spawn(task),
        Err(_) => DEFAULT_TOKIO_RUNTIME.spawn(task),
    }
}
