Os-specific extensions for Child

Required Methods§

Source

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

🔬This is a nightly-only experimental API. (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.

Source

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

🔬This is a nightly-only experimental API. (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.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
