Struct cap_std::net::TcpStream

pub struct TcpStream { /* fields omitted */ }

A TCP stream between a local and a remote socket.

This corresponds to std::net::TcpStream.

Note that this TcpStream has no connect method. To create a TcpStream, you must first obtain a Catalog permitting the address, and then call Catalog::connect_tcp_stream.

Implementations

impl TcpStream

pub unsafe fn from_std(std: TcpStream) -> Self

Constructs a new instance of Self from the given std::net::TcpStream.

Safety

std::net::TcpStream is not sandboxed and may access any address that the host process has access to.

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

This corresponds to std::net::TcpStream::shutdown.

Returns the read timeout of this socket.

This corresponds to std::net::TcpStream::read_timeout.

pub fn write_timeout(&self) -> Result<Option<Duration>>

Returns the write timeout of this socket.

This corresponds to std::net::TcpStream::write_timeout.

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

Receives data on the socket from the remote address to which it is connected, without removing that data from the queue.

This corresponds to std::net::TcpStream::peek.

pub fn set_nodelay(&self, nodelay: bool) -> Result<()>

Sets the value of the TCP_NODELAY option on this socket.

This corresponds to std::net::TcpStream::set_nodelay.

pub fn nodelay(&self) -> Result<bool>

Gets the value of the TCP_NODELAY option on this socket.

This corresponds to std::net::TcpStream::nodelay.

pub fn set_ttl(&self, ttl: u32) -> Result<()>

Sets the value for the IP_TTL option on this socket.

This corresponds to std::net::TcpStream::set_ttl.

pub fn ttl(&self) -> Result<u32>

Gets the value of the IP_TTL option for this socket.

This corresponds to std::net::TcpStream::ttl.

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

Gets the value of the SO_ERROR option on this socket.

This corresponds to std::net::TcpStream::take_error.

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

Moves this TCP stream into or out of nonblocking mode.

This corresponds to std::net::TcpStream::set_nonblocking.
