Enum HandlerError 

#[non_exhaustive]
pub enum HandlerError {
    HandlerStop {
        state: Option<Value>,
    },
    Other(Box<dyn Error + Sync + Send>),
}

Errors that can occur during update processing.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

HandlerStop

A handler explicitly requested dispatch to stop, optionally carrying state.

Fields

state: Option<Value>

Optional state data carried by the stop signal.

Other(Box<dyn Error + Sync + Send>)

A wrapped error from a handler or Telegram API call.
