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

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
