Detailed Description

template<typename Fn>
struct GusdUT_StaticValHolder< Fn >

Helper for creating a static value, whose construction is deferred and backed by a lock. This is similar to UT_SingletonWithLock, except that the value held is the result of calling method, rather than constructing an object.

Example usage:

T* someFn();
static auto staticVal(GusdUT_StaticVal(someFn));
// Function is not exec'd until accessed.
// To access:
T* val = *staticVal;
// Or:
staticVal->method();
