Function relay_event_normalization::set_default_transaction_source

pub fn set_default_transaction_source(event: &mut Event)

Set a default transaction source if it is missing, but only if the transaction name was extracted as a metrics tag. This behavior makes it possible to identify transactions for which the transaction name was not extracted as a tag on the corresponding metrics, because source == null <=> transaction name == null See relay_server::metrics_extraction::transactions::get_transaction_name.
