Trait WatchReceiverExt

pub trait WatchReceiverExt<T> {
    // Required method
    async fn wait_for_change(
        &mut self,
        f: impl Fn(&T) -> bool,
    ) -> Result<(), RecvError>;
}

Required Methods

async fn wait_for_change( &mut self, f: impl Fn(&T) -> bool, ) -> Result<(), RecvError>
