Function r_namespace_name 

fn r_namespace_name(name: &str) -> String

The argument of a raw export(...) NAMESPACE directive: bare for a syntactic name, a double-quoted string for an operator such as [[ (export([[) does not parse). Must match r_namespace_name in miniextendr-macros’ naming module, which writes the method blocks’ directive for the same generic; roxygen2 only merges identical lines.
