Expand description

TODO: this should be crate-private. currently needed for models testing

Fields§

§poll: Poll§events: Events§server: TcpListener§backlog_pending: bool

Set when the last drain stopped at MAX_ACCEPTS_PER_POLL. The mio registration is edge-triggered, so a backlog left behind does not re-arm readiness on its own: the next poll has to look for it instead of blocking.

Implementations§

source§

impl BootstrapTcpListener

source

pub fn create( addr: &SocketAddr, ) -> Result<(BootstrapListenerStopHandle, Self), BootstrapError>

Setup a mio-listener that functions as a select! on a connection, or a waker

  • addr - the address to listen on
source

pub fn poll(&mut self) -> Result<PollEvent, BootstrapError>

Poll the listener for new connections

At most MAX_ACCEPTS_PER_POLL connections are returned per call, so that the caller gets to apply admission control before the rest of the backlog is pulled into the process.
