Implementations

impl AddrIncoming

pub(super) fn new(addr: &SocketAddr) -> Result<Self>

pub(super) fn from_std(std_listener: StdTcpListener) -> Result<Self>

pub fn bind(addr: &SocketAddr) -> Result<Self>

Creates a new AddrIncoming binding to provided socket address.

pub fn from_listener(listener: TcpListener) -> Result<Self>

Creates a new AddrIncoming from an existing tokio::net::TcpListener.

pub fn local_addr(&self) -> SocketAddr

Get the local address bound to this listener.

pub fn set_keepalive(&mut self, time: Option<Duration>) -> &mut Self

Set the duration to remain idle before sending TCP keepalive probes.

If None is specified, keepalive is disabled.

pub fn set_keepalive_interval( &mut self, interval: Option<Duration>, ) -> &mut Self

Set the duration between two successive TCP keepalive retransmissions, if acknowledgement to the previous keepalive transmission is not received.

pub fn set_keepalive_retries(&mut self, retries: Option<u32>) -> &mut Self

Set the number of retransmissions to be carried out before declaring that remote end is not available.

pub fn set_nodelay(&mut self, enabled: bool) -> &mut Self

Set the value of TCP_NODELAY option for accepted connections.

pub fn set_sleep_on_errors(&mut self, val: bool)

Set whether to sleep on accept errors.

A possible scenario is that the process has hit the max open files allowed, and so trying to accept a new connection will fail with EMFILE. In some cases, it’s preferable to just wait for some time, if the application will likely close some files (or connections), and try to accept the connection again. If this option is true, the error will be logged at the error level, since it is still a big deal, and then the listener will sleep for 1 second.

In other cases, hitting the max open files should be treat similarly to being out-of-memory, and simply error (and shutdown). Setting this option to false will allow that.

Default is true.

fn poll_next_(&mut self, cx: &mut Context<'_>) -> Poll<Result<AddrStream>>

Trait Implementations

impl Accept for AddrIncoming

type Conn = AddrStream
