Required Methods§
sourcefn pidfd(&self) -> Result<&PidFd>
🔬This is a nightly-only experimental API. (linux_pidfd

fn pidfd(&self) -> Result<&PidFd>
linux_pidfd
#82971)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) -> Result<PidFd, Self>where

linux_pidfd
#82971)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.
