Enum AnySubscriptionCallback

pub enum AnySubscriptionCallback<T>
where
    T: Message,
{
    Regular(Box<dyn FnMut(T) + Send>),
    RegularWithMessageInfo(Box<dyn FnMut(T, MessageInfo) + Send>),

    LoanedWithMessageInfo(Box<dyn for<'a> FnMut(ReadOnlyLoanedMessage<'a, T>, MessageInfo) + Send>),
}

An enum capturing the various possible function signatures for subscription callbacks.

The correct enum variant is deduced by the SubscriptionCallback trait.

Boxed(Box<dyn FnMut(Box<T>) + Send>)

A callback with only the boxed message as an argument.

BoxedWithMessageInfo(Box<dyn FnMut(Box<T>, MessageInfo) + Send>)

A callback with the boxed message and the message info as arguments.

Loaned(Box<dyn for<'a> FnMut(ReadOnlyLoanedMessage<'a, T>) + Send>)
