Syntax

Remarks

TUniqueFunction<FuncType>

See the class definition for intended usage.

TUniqueFunction<FuncType>

Used like TFunction above, but is move-only. This allows non-copyable functors to be bound to it.

Example:

TUniquePtr<FThing> Thing = MakeUnique<FThing>();

TFunction <void()> CopyableFunc = [Thing = MoveTemp(Thing)](){ Thing->DoSomething(); }; // error - lambda is not copyable TUniqueFunction<void()> MovableFunc = [Thing = MoveTemp(Thing)](){ Thing->DoSomething(); }; // ok

void Foo(TUniqueFunction<void()> Func); Foo(MovableFunc); // error - TUniqueFunction is not copyable Foo(MoveTemp(MovableFunc)); // ok
