How to hide terminal shell on server application like Warp in Windows?-CodePudding

I have a small warp server project on Windows that listen to a particular port and do something whenever I send a command to it by REST (for example: POST http://10.10.10.1:5000/print). It's a small client for printing PDF / receipt directly from another computer.

It works. But my problem is when I had to package the whole project, the Rust compiler give me an executable file (.exe). The application displays a terminal window when I run it. I want this terminal to be hidden somehow.

I try to run the program as a windows service (by using NSSM). It doesn't work for me since I had to access the printer. Windows doesn't allow my app to access any devices or any other executable as a windows service. (The reasons are explained here:

Do anyone know how to hide or get rid of it ?

Start program in background.

After lot of searching, It turns out to be easier than I thought. Just add

#![windows_subsystem = "windows"]

on top of your main.rs file. (for rust > 1.18) and the terminal is gone.
