Struct Fd 

pub struct Fd { /* private fields */ }

A file descriptor that can be sent across a vox connection.

Construct one with Fd::new from anything that owns a descriptor (OwnedFd, File, UnixStream, …). After the value has been received on the far side, take ownership with Fd::into_owned_fd or borrow it with Fd::as_raw_fd.

Serializing an Fd duplicates its descriptor into the transport’s SCM_RIGHTS batch (the source Fd keeps ownership), so a response may be encoded more than once — the operation store’s replay-seal pass and the wire pass — and the encoder’s size/write double-call is deduped by the Fd value’s address.

Implementations

impl Fd

pub fn new(fd: impl Into<OwnedFd>) -> Self

Wrap an owned descriptor for sending.

pub fn as_raw_fd(&self) -> Option<RawFd>

Borrow the raw descriptor without taking ownership. None if it has already been taken.

pub fn into_owned_fd(self) -> Option<OwnedFd>

Take the owned descriptor out of this Fd.

pub fn into_raw_fd(self) -> Option<RawFd>

Take the descriptor as a raw, owned RawFd. The caller is responsible for closing it.
