Trait ChildExt

Required Methods

fn pidfd(self: &Self) -> Result<&PidFd>

Obtains a reference to the PidFd created for this Child, if available.

A pidfd will only be available if its creation was requested with create_pidfd when the corresponding Command was created.

Even if requested, a pidfd may not be available due to an older version of Linux being in use, or if some other error occurred.

fn into_pidfd(self: Self) -> crate::result::Result<PidFd, Self>
where
    Self: Sized

Returns the PidFd created for this Child, if available. Otherwise self is returned.

A pidfd will only be available if its creation was requested with create_pidfd when the corresponding Command was created.

Taking ownership of the PidFd consumes the Child to avoid pid reuse races. Use pidfd and BorrowedFd::try_clone_to_owned if you don't want to disassemble the Child yet.

Even if requested, a pidfd may not be available due to an older version of Linux being in use, or if some other error occurred.
