Function deserialize 

pub fn deserialize(payload: &str) -> Result<Box<dyn Queueable>, Error>

Attempts to deserialize a JSON string into a boxed Queueable trait object.

This function uses Serde (with typetag::serde) to deserialize the given payload string into a Box<dyn Queueable>, allowing dynamic dispatch to specific job implementations at runtime.

Parameters

• payload: A JSON-encoded string representing a serialized Queueable.

Returns

• Ok(Box<dyn Queueable>) if the deserialization is successful.
• Err(serde_json::Error) if deserialization fails (e.g., invalid JSON format or missing fields).

Example

use crate::traits::Queueable;

// Assume `serialized_job` is a valid JSON representation of a type implementing `Queueable`.
let serialized_job = r#"{
    "type": "MyConcreteJob",
    "some_field": "some_value"
}"#;

match deserialize(serialized_job) {
    Ok(job) => {
        // Now you can call job.handle(), etc.
        println!("Job deserialized successfully!");
    }
    Err(e) => eprintln!("Failed to deserialize job: {}", e),
}
