How can one spawn a process without opening up a window?

[amitka-rnd]

I'm compiling my exe with #![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]
an issue I've noticed that whenever I trigger a new command it opens up a new window.

I've used Process before where I could've just pass a flag to creation_flags which indicates to not spawn a new window.

is there a solution for cmd_lib?

I don't have windows dev machine, but I guess to fix it you can just pass extra flags when calling Command::new in process.rs. Patch is also welcome.
