-------------------------------------

             Summary: libprocess: Add explicit to single argument constructors
                 Key: MESOS-1057
                 URL: https://issues.apache.org/jira/browse/MESOS-1057
             Project: Mesos
          Issue Type: Improvement
          Components: libprocess
            Reporter: Bernd Mathiske
            Assignee: Bernd Mathiske
            Priority: Minor


Exactly like MESOS-1055, just splitting out the task for lib process into a separate issue.

>From the google style guide:
Normally, if a constructor takes one argument, it can be used as a conversion. For instance, if you define Foo::Foo(string name) and then pass a string to a function that expects a Foo, the constructor will be called to convert the string into a Foo and will pass the Foo to your function for you. This can be convenient but is also a source of trouble when things get converted and new objects created without you meaning them to. Declaring a constructor explicit prevents it from being invoked implicitly as a conversion.
Implicit conversions should be the exception to avoid unwanted and unexpected behaviour.
