Struct JoinedRow 

pub struct JoinedRow<'a> { /* private fields */ }

JoinedRow — a RowAccess adapter over several named topic sources. Dotted paths topic.field.sub are split at the first .: the prefix matches the topic name, the rest is forwarded to its RowAccess::get.

If no topic source knows the prefix, the whole path is forwarded to all sources (fallback for undotted field references).
