move

Hello here is a test code I wrote on MSVC12. Could someone tell me why the std::move when I pass parameters to the thread are not converting the variabes to RValue refs?? And what I should do. Thank you! ///some arbitrary long task std::string DumpFile(std::string path){ std::this_thread::sleep_for(std::chrono::seconds(10)); return path; } void run_promise(std::promise<std::string> &&_prom, std::string &&_path){ try { std::string val = DumpFile(std::move(_path)); _prom.set_value(val); } catch (...) { _prom.set_exception(std::current_exception()); } } std::future<std::string> ADumpFile(std:

I'm having a lot of fun trying to solve the robot simulator Exercism exercise , but I'm facing a value moving problem for which I don't seem to be able to come up with an elegant solution: impl Robot { pub fn new(x: isize, y: isize, d: Direction) -> Self { Robot { position: Coordinate { x: x, y: y }, direction: d } } pub fn turn_right(mut self) -> Self { match self.direction { // ... }; self } pub fn turn_left(mut self) -> Self { match self.direction { // ... }; self } pub fn advance(mut self) -> Self { match self.direction { // ... }; self } pub fn instructions(self, instructions: &str) ->

Are there differences when I use that functions? Why should I use one instead of the other one... copy() copies the file - you now have 2 files, and for large files, this can take very long rename() changes the file's name, which can mean moving it between directories. move_uploaded_file() is basically the same as rename() , but it will only work on files that have been uploaded via PHP's upload mechanism. This is a security feature that prevents users from tricking your script into showing them security-relevant data. In the future, I suggest looking up such information in the PHP Manual

I am trying to use monkeyrunner to simulate complex touch events. A swipe from a to b with... device.drag((300,500),(300,650),0.5,50) works great but a complex movement from a to b to c doesn't work trying with that device.touch(100,500, 'DOWN') device.touch(300,500, 'MOVE') device.touch(300,400, 'MOVE') device.touch(300,400, 'UP') Was seaching for a solution and found this.. https://android-review.googlesource.com/#/c/50991/ Is this already implemenet in the offical android sdk? or did i have to compile it or something else and how it works? I dont really know but i think this side is the

I have ownership of an array of size 3 and I would like to iterate on it, moving the elements out as I go. Basically, I would like to have IntoIterator implemented for a fixed-sized array. Since arrays don't implement this trait in the standard library (I understand why), is there a workaround to get the desired effect? My objects are not Copy nor Clone . I'd be okay creating a Vec from the array and then iterating into the Vec , but I'm not even sure how to do that. (For information, I'd like to fulfill an array of Complete ) Here is a simple example of the situation (with a naive iter()

I have a powershell script that takes all of the files in one directory, renames the first one and moves it, and then goes to the next file. Sometimes there will be multiple files that get renamed to the same name (because of the system that it's going to, not ideal and will have to change) and was overwriting files that shouldn't have been getting overwritten with -force. I need all of the files to move but also have unique names so we have them available in the destination location. Is there an easy way to have it automatically rename so it would look like: 123.txt 123(1).txt 123(2).txt or
