TUniqueFunction | Unreal Engine 5.8 Documentation

TUniqueFunction

See the class definition for intended usage.

TUniqueFunction

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

Example:

TUniquePtr Thing = MakeUnique();

TFunction CopyableFunc = Thing = Move(Thing){ Thing->DoSomething(); }; // error - lambda is not copyable TUniqueFunction MovableFunc = Thing = Move(Thing){ Thing->DoSomething(); }; // ok

void Foo(TUniqueFunction Func); Foo(MovableFunc); // error - TUniqueFunction is not copyable Foo(Move(MovableFunc)); // ok
