Struct tokio_uds::UnixStream

[+] Show declaration

pub struct UnixStream { /* fields omitted */ }

[−] Expand description

A structure representing a connected Unix socket.

This socket can be connected directly with UnixStream::connect or accepted from a listener with UnixListener::incoming. Additionally, a pair of anonymous Unix sockets can be created with UnixStream::pair.

Methods

impl UnixStream

[−]

pub fn connect<P>(path: P) -> ConnectFuture where     P: AsRef<Path>,

[−]

Connects to the socket named by path.

This function will create a new Unix socket and connect to the path specified, associating the returned stream with the default event loop's handle.

pub fn from_std(stream: UnixStream, handle: &Handle) -> Result<UnixStream>

[−]

Consumes a UnixStream in the standard library and returns a nonblocking UnixStream from this crate.

The returned stream will be associated with the given event loop specified by handle and is ready to perform I/O.

pub fn pair() -> Result<(UnixStream, UnixStream)>

[−]

Creates an unnamed pair of connected sockets.

This function will create a pair of interconnected Unix sockets for communicating back and forth between one another. Each socket will be associated with the event loop whose handle is also provided.

pub fn poll_read_ready(&self, ready: Ready) -> Poll<Ready, Error>

[−]

Test whether this socket is ready to be read or not.

pub fn poll_write_ready(&self) -> Poll<Ready, Error>

[−]

Test whether this socket is ready to be written to or not.

pub fn local_addr(&self) -> Result<SocketAddr>

[−]

Returns the socket address of the local half of this connection.

pub fn peer_addr(&self) -> Result<SocketAddr>

[−]

Returns the socket address of the remote half of this connection.

pub fn peer_cred(&self) -> Result<UCred>

[−]

Returns effective credentials of the process which called connect or socketpair.

pub fn take_error(&self) -> Result<Option<Error>>

[−]

Returns the value of the SO_ERROR option.

pub fn shutdown(&self, how: Shutdown) -> Result<()>

[−]

Shuts down the read, write, or both halves of this connection.

This function will cause all pending and future I/O calls on the specified portions to immediately return with an appropriate value (see the documentation of Shutdown).
