Struct base::sys::unix::net::UnixSeqpacket

impl UnixSeqpacket

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

Creates a pair of connected SOCK_SEQPACKET sockets.

Both returned file descriptors have the CLOEXEC flag set.

impl UnixSeqpacket

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

Open a SOCK_SEQPACKET connection to socket named by path.

§Arguments

path - Path to SOCK_SEQPACKET socket

§Returns

A UnixSeqpacket structure point to the socket

§Errors

Return io::Error when error occurs.

pub fn try_clone(&self) -> Result<Self>

Clone the underlying FD.

pub fn get_readable_bytes(&self) -> Result<usize>

Gets the number of bytes that can be read from this socket without blocking.

pub fn next_packet_size(&self) -> Result<usize>

Gets the number of bytes in the next packet. This blocks as if recv were called, respecting the blocking and timeout settings of the underlying socket.

pub fn send(&self, buf: &[u8]) -> Result<usize>

Write data from a given buffer to the socket fd

§Arguments

buf - A reference to the data buffer.

§Returns

usize - The size of bytes written to the buffer.

§Errors

Returns error when libc::write failed.

pub fn recv(&self, buf: &mut [u8]) -> Result<usize>

Read data from the socket fd to a given buffer

§Arguments

buf - A mut reference to the data buffer.

§Returns

usize - The size of bytes read to the buffer.

§Errors

Returns error when libc::read failed.

pub fn recv_to_vec(&self, buf: &mut Vec<u8>) -> Result<()>

Read data from the socket fd to a given Vec, resizing it to the received packet’s size.

§Arguments

buf - A mut reference to a Vec to resize and read into.

§Errors

Returns error when libc::read or get_readable_bytes failed.

pub fn recv_as_vec(&self) -> Result<Vec<u8>>

Read data from the socket fd to a new Vec.

§Returns

vec - A new Vec with the entire received packet.

§Errors

Returns error when libc::read or get_readable_bytes failed.

fn set_timeout(&self, timeout: Option<Duration>, kind: c_int) -> Result<()>

pub fn set_read_timeout(&self, timeout: Option<Duration>) -> Result<()>

Sets or removes the timeout for read/recv operations on this socket.

pub fn set_write_timeout(&self, timeout: Option<Duration>) -> Result<()>

Sets or removes the timeout for write/send operations on this socket.

pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>

Sets the blocking mode for this socket.
