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
