Struct miri::shims::unix::unnamed_socket::AnonSocket

source ·
struct AnonSocket {
    readbuf: Option<RefCell<Buffer>>,
    peer_fd: OnceCell<WeakFileDescriptionRef>,
    peer_lost_data: Cell<bool>,
    is_nonblock: bool,
}
Expand description

One end of a pair of connected unnamed sockets.

Fields§

§readbuf: Option<RefCell<Buffer>>

The buffer we are reading from, or None if this is the writing end of a pipe. (In that case, the peer FD will be the reading end of that pipe.)

§peer_fd: OnceCell<WeakFileDescriptionRef>

The AnonSocket file descriptor that is our “peer”, and that holds the buffer we are writing to. This is a weak reference because the other side may be closed before us; all future writes will then trigger EPIPE.

§peer_lost_data: Cell<bool>

Indicates whether the peer has lost data when the file description is closed. This flag is set to true if the peer’s readbuf is non-empty at the time of closure.

§is_nonblock: bool
