[Joylei]

please try the code of perf branch, and let me know if it's working or not.

rseip={git="https://github.com/Joylei/eip-rs", branch="perf"}

This backtrace is from the current code

[Joylei]

please try the perf branch

[GeneL]

It does not compile:

This is the code: let instance_id = 0x627; //0x376; //0x83b; //0x189; // here use a known instance_id, please uncomment below line to fetch one from PLC controller. //let instance_id = first_struct_instance(&mut client).await?.unwrap(); let template = client.find_template(instance_id).await?; println!("template instance:\n{:?}", template); let info = client.read_template(&template).call().await?; println!("template definition:\n{:?}", info);

This is the response:

error[E0716]: temporary value dropped while borrowed --> src/main.rs:36:17	36	let info = client.read_template(&template).call().await?;	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - temporary value is freed at the end of this statement
creates a temporary which is freed while still in use
37	println!("template definition:\n{:?}", info);
---- borrow later used here

= note: consider using a let binding to create a longer lived value

For more information about this error, try rustc --explain E0716. warning: rseip (bin "rseip") generated 6 warnings error: could not compile rseip due to previous error; 6 warnings emitted

change your code like this

{
        let mut req = client.read_template(&template);
        let info = req.call().await?;
        println!("template definition:\n{:?}", info);
    }

[GeneL]

YES!! It works!
