)
Remarks
Execute a given function asynchronously.
Usage examples:
// using global function int TestFunc() { return 123; }
TUniqueFunction
// using lambda TUniqueFunction
auto Result = Async(EAsyncExecution::Thread, Task);
// using inline lambda auto Result = Async(EAsyncExecution::Thread, { return 123; } A TFuture object that will receive the return value from the function.
