I've imported some code pieces from a third party project into my C++11 project. The third party project uses optional-lite [1], though I'm using Boost heavily in the project and want to keep dependency on other libraries low.
There is boost::optional
, but unlike the c++17 counterpart it does not have nullopt
.
What's the Boost equivalent to nullopt
?
(Note: Boost version is 1.69)
The equivalent is boost::none
. See optional(none_t)
.
