Undefined Behavior with StreamExt::collect

[kalkronline]

The following snippet produces undefined behavior.

use std::io;
use rseip::precludes::{AbEipClient, PortSegment, AbService};
use futures::stream::StreamExt;

async fn init() -> io::Result<()> {
    let mut client = AbEipClient::new_host_lookup("10.0.10.70")
        .await
        .map_err(|e| io::Error::new(io::ErrorKind::Other, e))?
        .with_connection_path(PortSegment::default());
    
    let tags = client
        .list_tag()
        .call()
        .collect::<Vec<_>>()
        .await
        .into_iter()
        .collect::<Result<Vec<_>, _>>()
        .map_err(|e| io::Error::new(io::ErrorKind::Other, e))?;
    
    for tag in tags {
        println!("{tag:?}")
    }
}

Output:

list_tag() or other methods would keep references to underline bytes.

It's better to iterate the result immediately or convert it to your own data structure.
