Summary: Add variadic constructor for Option Key: MESOS-5072 URL: https://issues.apache.org/jira/browse/MESOS-5072 Project: Mesos Issue Type: Improvement Components: stout Reporter: Benjamin Bannier Currently an {{Option<T>}} can be constructed from an {{U}} if in turn a {{T}} is constructable from an {{U}}, e.g., {code} // Construct a std::string from a string literal. Option<string> s{"fnord"}; {code} We should extend this to permit this kind of construct from more than one parameter, i.e., {code} // Construct a vector of strings from a string initializer list. Option<vector<string>> v{"Browny", "Whitey", "Blacky"}; {code} Currently users need to duplicate the type which e.g., poses the danger of inadvertently type conversions, {code} Option<vector<string>> v{<vector<string>>{"Browny", "Whitey", "Blacky"}}; {code} It seems just making the {{U}} in the respective {{Option}} constructor variadic would already be enough to support this, but it would be highly desirable to remove explicit, redundant types in existing constructions of {{Options}} in the code base. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
