Function penguin::util::wait_for_proxy

pub async fn wait_for_proxy(target: &ProxyTarget, poll_period: Duration)

Repeatedly tries to connect to the given proxy via TCP, returning once a connection was established.

After each attempt, this function waits for poll_period before trying again. If the proxy target is never reachable, this function’s future never resolves. To stop this function after some timeout, use some external functions, e.g. tokio::time::timeout.

This function can be used just before calling Controller::reload to make sure the proxy server is ready. This avoids the user seeing “Cannot reach proxy target”.
