Struct InheritableChannel

pub struct InheritableChannel<TX, RX>(/* private fields */);

A Channel<TX, RX> whose internal (UNIX domain socket) file descriptor will persist in all child proceses (except for those which explicitly close it), and which only provides conversions to/from file descriptors, and a way to disable inheritance (i.e. re-enabling CLOEXEC semantics on it).

Implementations

impl InheritableChannel<Never, (PresentableImageId, OwnedFd)>

pub fn extra_args_for_client_spawning(&self) -> [String; 1]

pub fn from_process_args_in_client() -> Result<InheritableChannel<Never, (PresentableImageId, OwnedFd)>, Error>

impl<TX, RX> InheritableChannel<TX, RX>

pub fn into_uninheritable(self) -> Result<Channel<TX, RX>, Error>

Disable child process inheritance, i.e. re-add the CLOEXEC flag (via try_clone_to_owned which uses fcntl(F_DUPFD_CLOEXEC)).

Trait Implementations

impl<TX, RX> AsFd for InheritableChannel<TX, RX>

fn as_fd(&self) -> BorrowedFd<'_>

Borrows the file descriptor.

impl<TX, RX> From<OwnedFd> for InheritableChannel<TX, RX>

fn from(fd: OwnedFd) -> InheritableChannel<TX, RX>

Converts to this type from the input type.
