pub trait NoWindow {
// Required method
fn no_window(&mut self) -> &mut Self;
}Expand description
Spawn a child without opening a console window for it.
Every crate that spawns a child on Windows needs the same three lines:
#[cfg(windows)], use std::os::windows::process::CommandExt,
cmd.creation_flags(CREATE_NO_WINDOW). Forgetting them is silent, and shows up
only as a console flashing over the splash on a user’s desktop (#2171, #2173,
#3788). This trait makes it one call that is a no-op off Windows, and works for
both std::process::Command and tokio::process::Command.
creation_flags replaces the flags, it does not OR them, so a spawn that needs
other flags too (CREATE_SUSPENDED | CREATE_NO_WINDOW) or a different one
(CREATE_NEW_CONSOLE) still calls creation_flags itself.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
