Struct ReadOnlyLoanedMessage

Source 
pub struct ReadOnlyLoanedMessage<'a, T>
where
    T: Message,
{ /* private fields */ }
Expand description

A message that is owned by the middleware, loaned out for reading.

It dereferences to a &T::RmwMsg. That is, if T is already an RMW-native message, it’s the same as &T, and otherwise it’s the corresponding RMW-native message.

This type is returned by Subscription::take_loaned() and may be used in subscription callbacks.

The loan is returned by dropping the ReadOnlyLoanedMessage.
