Trait Implementations

impl SocketOps for ZxioBackedSocket

fn get_socket_info( &self, ) -> Result<(SocketDomain, SocketType, SocketProtocol), Errno>

Returns the domain, type and protocol of the socket. This is only used for socket that are build without previous knowledge of this information, and can be ignored if all sockets are build with it.

fn connect( &self, socket: &SocketHandle, current_task: &CurrentTask, peer: SocketPeer, ) -> Result<(), Errno>

Connect the socket to the listening peer. On success a new socket is created and added to the accept queue.

fn listen( &self, _socket: &Socket, backlog: i32, _credentials: ucred, ) -> Result<(), Errno>

Start listening at the bound address for connect calls.

fn accept( &self, socket: &Socket, current_task: &CurrentTask, ) -> Result<SocketHandle, Errno>

Returns the eariest socket on the accept queue of this listening socket. Returns EAGAIN if the queue is empty.

fn bind( &self, socket: &Socket, current_task: &CurrentTask, socket_address: SocketAddress, ) -> Result<(), Errno>

Binds this socket to a socket_address.

fn read( &self, socket: &Socket, current_task: &CurrentTask, data: &mut dyn OutputBuffer, flags: SocketMessageFlags, ) -> Result<MessageReadInfo, Errno>

Reads the specified number of bytes from the socket, if possible.

fn write( &self, socket: &Socket, current_task: &CurrentTask, data: &mut dyn InputBuffer, dest_address: &mut Option<SocketAddress>, ancillary_data: &mut Vec<AncillaryData>, ) -> Result<usize, Errno>

Writes the data in the provided user buffers to this socket.

fn wait_async( &self, _socket: &Socket, _current_task: &CurrentTask, waiter: &Waiter, events: FdEvents, handler: EventHandler, ) -> WaitCanceler

Queues an asynchronous wait for the specified events on the waiter. Note that no wait occurs until a wait functions is called on the waiter.

fn query_events( &self, _socket: &Socket, _current_task: &CurrentTask, ) -> Result<FdEvents, Errno>

Return the events that are currently active on the socket.

fn shutdown( &self, _socket: &Socket, how: SocketShutdownFlags, ) -> Result<(), Errno>

Shuts down this socket according to how, preventing any future reads and/or writes.

fn close(&self, current_task: &CurrentTask, socket: &Socket)

Close this socket.

fn getsockname(&self, socket: &Socket) -> Result<SocketAddress, Errno>

Returns the name of this socket.

fn getpeername(&self, _socket: &Socket) -> Result<SocketAddress, Errno>

Returns the name of the peer of this socket, if such a peer exists.

fn setsockopt( &self, _socket: &Socket, current_task: &CurrentTask, level: u32, optname: u32, optval: SockOptValue, ) -> Result<(), Errno>

Sets socket-specific options.

fn getsockopt( &self, _socket: &Socket, _current_task: &CurrentTask, level: u32, optname: u32, optlen: u32, ) -> Result<Vec<u8>, Errno>

Retrieves socket-specific options.

fn to_handle( &self, _socket: &Socket, _current_task: &CurrentTask, ) -> Result<Option<NullableHandle>, Errno>

Return a handle that allows access to this file descritor through the zxio protocols.

fn ioctl( &self, socket: &Socket, _file: &FileObject, current_task: &CurrentTask, request: u32, arg: SyscallArg, ) -> Result<SyscallResult, Errno>

Implements ioctl.
