Enum Stdin 

pub enum Stdin {
    Closed,
    Piped,
}

What the child’s stdin is connected to.

Most CLIs get everything as arguments and want Closed: a child that inherits a terminal’s stdin can block forever waiting for input nobody is typing. A child that answers — a JSON-RPC server over stdio — needs Piped and ProcessHandle::write_line.

Variants

Closed

Piped
