/*
|
|
* `SharedFunction` implements a pattern of a shared callable object that
|
|
* contains the same executable inside. It's similar to `std::function` with
|
|
* one important difference: when the object is copied, the stored function (and
|
|
* captured values) are shared between instances (not copied). `SharedFunction`
|
|
* can be stored inside `std::function` because it's callable. It useful in some
|
|
* scenarios, such as:
|
|
* - When captured by `std::function` arguments are not copyable;
|
|
* - When we need to replace the content of the callable later on the go.
