UnixSeqpacket

Implementations

impl UnixSeqpacket

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

Creates an unnamed pair of connected sockets.

pub async fn connect<P: AsRef<Path>>(path: P) -> Result<Self>

Connects the socket to the specified address.

pub async fn connect_addr(addr: SocketAddr) -> Result<Self>

Connects the socket to an address.

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 async fn readable(&self, relaxed: bool) -> Result<()>

Wait for read readiness. Note: Do not use it before every io. It is different from other runtimes!

Everytime call to this method may pay a syscall cost. In uring impl, it will push a PollAdd op; in epoll impl, it will use use inner readiness state; if !relaxed, it will call syscall poll after that.

If relaxed, on legacy driver it may return false positive result. If you want to do io by your own, you must maintain io readiness and wait for io ready with relaxed=false.

pub async fn writable(&self, relaxed: bool) -> Result<()>

Wait for write readiness. Note: Do not use it before every io. It is different from other runtimes!

Everytime call to this method may pay a syscall cost. In uring impl, it will push a PollAdd op; in epoll impl, it will use use inner readiness state; if !relaxed, it will call syscall poll after that.

If relaxed, on legacy driver it may return false positive result. If you want to do io by your own, you must maintain io readiness and wait for io ready with relaxed=false.

pub async fn send_to<T: IoBuf, P: AsRef<Path>>( &self, buf: T, path: P, ) -> BufResult<usize, T>

Sends data on the socket to the given address. On success, returns the number of bytes written.

pub async fn recv_from<T: IoBufMut>( &self, buf: T, ) -> BufResult<(usize, SocketAddr), T>

Receives a single datagram message on the socket. On success, returns the number of bytes read and the origin.

pub async fn send<T: IoBuf>(&self, buf: T) -> BufResult<usize, T>

Sends data on the socket to the remote address to which it is connected.

pub async fn recv<T: IoBufMut>(&self, buf: T) -> BufResult<usize, T>

Receives a single datagram message on the socket from the remote address to which it is connected. On success, returns the number of bytes read.
