Struct hyper::server::conn::AddrIncoming

#[must_use = "streams do nothing unless polled"]
pub struct AddrIncoming { /* fields omitted */ }

A stream of connections from binding to an address.

Methods

impl AddrIncoming

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

Creates a new AddrIncoming binding to provided socket address.

pub fn local_addr(&self) -> SocketAddr

Get the local address bound to this listener.

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

Set whether TCP keepalive messages are enabled on accepted connections.

If None is specified, keepalive is disabled, otherwise the duration specified will be the time to remain idle before sending TCP keepalive probes.

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.
