rosrust::tcpros::subscriber Failed to connect to topic each time a message arrive on it

Hi,

I may be missing something, but I noticed a strange behavior with a "simple rosrust subscriber". Here is some piece of code to expose my issue :

rosrust::subscribe("/dock", 2, |v: rosrust_msg::std_msgs::String| {
            rosrust::ros_info!("Received: {:?}", v);
}).unwrap();
 let rate = rosrust::rate(2.0);
    while rosrust::is_ok() {
        rate.sleep();
    }

I use the #113 tips to build the node with catkin and launch the node with roslaunch
.
After that when I : rostopic pub /dock std_msgs/String "data: 'hello, world.'",
I then got a log :

[2020-10-28T10:08:57Z ERROR rosrust::tcpros::subscriber] Failed to connect to topic '/dock'
    Caused by:Connection refused (os error 111)
[INFO @ src/(...)/main.rs:27]: Received: String { data: "hello, world." }

So message is properly received but I don't know why this error pop ...
Any advice ? Thank you very much!
