GET_VEC

The get_vec(...) method allows for async get requests of urls in a Vec<&str> form, e.g.

let api = API::new();

#[threads(2)]
api.get_vec(urls, DATA_PATH).await;

This would retrieve both files in the urls vec, and download them to the "src/" directory, using 2 async threads.

Included are the "header" and "threads" macro; header adding custom headers, and threads specifying the number of threads to open. By default, threads is set to 1.

Below is an example:

#[tokio::main]
fn main() {
    let mut api = API::new(); // runner required to be mut for header changes
    let SAVE_PATH: &str = "./data";

    // Visit the first api, needing only the User-Agent (with only 1 thread)
    //

    let api_1 = vec![
        "www.endpoint_1.xml",
        "www.endpoint_2.json"
    ];

    #[header("User-Agent", "example@email_domain.com")]
    api.get_vec(api_1, ).await;
    


    // Visit the second api, now needing an API key; referred to as "API-Token"
    // (Opening 2 threads at once)
    //

    let api_2 = vec![
        "www.endpoint_3.xml",
        "www.endpoint_4.csv"
    ];

    #[threads(2)]
    #[header("User-Agent", "example@email_domain.com")]
    #[header("API-Token", "XXXXXXXXX")]
    api.get_vec(api_2, ).await;
}

TODO!

• request_per_second wrapper + proc_macro
• add logger (with boolean option)
• add thiserror
• determine if get_vec can be defined with generic types
