Detailed Description

The ScopeOutAction class - guard-type class that allows points callback that will be called at the scope out.

Example:

void foo()
{
    int fd = open(...some args...);
    ScopeOutAction action([fd](){
        close(fd);
    });
 
    try
    {
        // some actions that can throw exception
    }
    catch(...)
    {
        throw; // Not best-practice, only for example
    }
}

In example above dtor of the action will be called before fd and we correctly close descriptor.
