Chapter 8. Utility Classes
In this chapter, we will cover the following recipes:
- Converting between different time units using
std::ratio - Converting between absolute and relative times with
std::chrono - Safely signalizing failure with
std::optional - Applying functions on tuples
- Quickly composing data structures with
std::tuple - Replacing
void*withstd::anyfor more type safety - Storing different types with
std::variant - Automatically handling resources with
std::unique_ptr - Automatically handling shared heap memory with
std::shared_ptr - Dealing with weak pointers to shared objects
- Simplifying resource handling of legacy APIs with smart pointers
- Sharing different member values of the same object
- Generating random numbers and choosing the right random number engine
- Generating random numbers and letting the STL shape specific distributions
