<cuda/std/variant>
|
|
======================
|
|
|
|
See the documentation of the standard header `\<variant\> <https://en.cppreference.com/w/cpp/header/variant>`_
|
|
|
|
Extensions
|
|
----------
|
|
|
|
- All features are available from C++14 onwards.
|
|
- All features are available at compile time if the different value types support it.
|
|
|
|
Restrictions
|
|
------------
|
|
|
|
- On device no exceptions are thrown in case of a bad access.
|
|
|
|
Cuda specific changes
|
|
---------------------
|
|
|
|
- ``cuda::std::visit`` utilizes recursion instead of the usual function
|
|
pointer array. This greatly improves runtime behavior, but comes at
|
|
the cost of increased compile times.
