Struct wasi_cap_std_sync::TcpListener
source · [−]pub struct TcpListener { /* private fields */ }
Expand description
A TCP socket server, listening for connections.
This corresponds to std::net::TcpListener
.
Note that this TcpListener
has no bind
method. To bind it to a socket
address, you must first obtain a Pool
permitting the address, and
then call Pool::bind_tcp_listener
.
Implementations
sourceimpl TcpListener
impl TcpListener
sourcepub fn from_std(std: TcpListener) -> TcpListener
pub fn from_std(std: TcpListener) -> TcpListener
Constructs a new instance of Self
from the given

instance
already has access to.
sourcepub fn local_addr(&self) -> Result<SocketAddr, Error>
pub fn local_addr(&self) -> Result<SocketAddr, Error>

sourcepub fn try_clone(&self) -> Result<TcpListener, Error>
pub fn try_clone(&self) -> Result<TcpListener, Error>

This corresponds to std::net::TcpListener::try_clone
.
sourcepub fn accept(&self) -> Result<(TcpStream, SocketAddr), Error>
pub fn accept(&self) -> Result<(TcpStream, SocketAddr), Error>
Accept a new incoming connection from this listener.
This corresponds to std::net::TcpListener::accept
.
sourcepub fn incoming(&self) -> Incoming<'_>
pub fn incoming(&self) -> Incoming<'_>
Returns an iterator over the connections being received on this listener.
This corresponds to std::net::TcpListener::incoming
.
sourcepub fn set_ttl(&self, ttl: u32) -> Result<(), Error>
pub fn set_ttl(&self, ttl: u32) -> Result<(), Error>
Sets the value for the IP_TTL
option on this socket.
This corresponds to std::net::TcpListener::set_ttl
.
sourcepub fn ttl(&self) -> Result<u32, Error>
pub fn ttl(&self) -> Result<u32, Error>
Gets the value of the IP_TTL
option for this socket.
This corresponds to std::net::TcpListener::ttl
.
sourcepub fn take_error(&self) -> Result<Option<Error>, Error>
pub fn take_error(&self) -> Result<Option<Error>, Error>
Gets the value of the SO_ERROR
option on this socket.
This corresponds to std::net::TcpListener::take_error
.
sourcepub fn set_nonblocking(&self, nonblocking: bool) -> Result<(), Error>
pub fn set_nonblocking(&self, nonblocking: bool) -> Result<(), Error>
Moves this TCP stream into or out of nonblocking mode.
This corresponds to std::net::TcpListener::set_nonblocking
.
