pub fn hide_console_window(cmd: &mut Command)Expand description
Start cmd without a console window, so an agent’s shell calls do not flash
consoles across the desktop on Windows (issue #228).
The tokio twin of leviath_sys::hide_console_window, which takes a
std::process::Command; as_std_mut reaches the one tokio wraps, so the
flag has a single implementation rather than a second copy of the #[cfg].
A no-op everywhere but Windows. Only for a child whose stdio is piped, which
is every caller here.
