Enum WatcherOperationError

pub enum WatcherOperationError<S: Debug, B: Update<S> + Debug> {
    EventStream(Error),
    Update(UpdateError),
    UnexpectedEnd {
        final_state: B,
        marker: PhantomData<S>,
    },
    UnexpectedEvent(Event),
}

UnexpectedEnd

Watcher event stream ended unexpectedly.

marker: PhantomData<S>

Marker for the state held alongside interface properties.

UnexpectedEvent(Event)

Formats the value using the given formatter.

impl<S: Debug, B> Display for WatcherOperationError<S, B>

where B: Debug + Update<S> + Debug,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
