Why don't you implement "toString" on your type?

   void toString(scope void delegate(const(char)[]) sink)
   {
       import std.format;
       formattedWrite(sink, `%s`, "MyStruct(");
       formattedWrite(sink, `"%s"`, name);
       formattedWrite(sink, `%s`, ", ");
       formattedWrite(sink, `%s`, buf.data);
       formattedWrite(sink, `%s`, ")");
   }
