QUESTION
According to cppreference.com:
The only data stored in a duration is a tick count of type Rep.
However, I've noticed that for example:
this_thread::sleep_for
takes sleep_duration
by const ref.
future::wait_for
likewise takes duration
by const ref.
etc.
(1) Any particular reason why they are not passed by value instead?
(1a) Does passing by const reference pessimize some possible constexpr
optimizations?
ANSWER
Answered 2017-Aug-17 at 16:27It was a judgement call. The cost for the common case of the "built-in" durations is small compared to the cost of what the function is going to do (sleep). And I didn't want to think about the cost of pass-by-value for a custom duration containing a custom Rep
that might be expensive to copy (e.g. BigNum).
