Struct HandlerPair

pub(crate) struct HandlerPair<T: Logger> {
    pub(crate) user_defined_handler: Option<Box<dyn Fn(&T) + Send>>,
    pub(crate) logging_handler: Option<Box<dyn Fn(&T) + Send>>,
}

Stores the two optional handlers enabled for an event type that implements the Logger trait, namely one logging handler, defined in logging, and one user-defined handler, passed to ReplicaSpec.

Note that the user-defined handler is expected to include all expected event-handling functionalities per event.

Fields

user_defined_handler: Option<Box<dyn Fn(&T) + Send>>

logging_handler: Option<Box<dyn Fn(&T) + Send>>

Implementations

impl<T: Logger> HandlerPair<T>

pub(crate) fn is_empty(&self) -> bool

pub(crate) fn new( log: bool, user_defined_handler: Option<Box<dyn Fn(&T) + Send>>, ) -> HandlerPair<T>

Creates a new HandlerPair with the user-defined handler, and the default logging handler if logging is enabled.
