fn create_pidfd(&mut self, val: bool) -> &mut Command
🔬This is a nightly-only experimental API. (
linux_pidfd #82971)Sets whether a PidFd should be created for the Child
spawned by this Command.
By default, no pidfd will be created.
The pidfd can be retrieved from the child with pidfd or take_pidfd.
A pidfd will only be created if it is possible to do so
in a guaranteed race-free manner (e.g. if the clone3 system call
is supported). Otherwise, pidfd will return an error.
