pub fn pb_mapper_server_addr(addr: Option<&str>) -> Result<String>Expand description
The relay address as configured: addr if given, else PB_MAPPER_SERVER.
Unresolved on purpose. A caller that hands the address to something which resolves it itself — the SDK client, for one — should pass the name along rather than resolve it here and stringify the result, which both duplicates the lookup and narrows a multi-address name down to one entry on the way.
