Serde Rename JSON Field

TODO: collapasable, copyable, download, etc

In Rust using serde_json how can I tell serde that pub struct PageJsonBlob { pub inital_options: InitialOptions, } that intial_options should look like INITIAL_OPTIONS in the JSON?To tell Serde to deserialize the field initial_options from the JSON key INITIAL_OPTIONS, you can use the #[serde(rename = "INITIAL_OPTIONS")] attribute on the field.

Here's the updated PageJsonBlob struct:

use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, Debug)]
pub struct PageJsonBlob {
    #[serde(rename = "INITIAL_OPTIONS")]
    pub initial_options: InitialOptions,
}

// Your InitialOptions struct implementation
#[derive(Serialize, Deserialize, Debug)]
pub struct InitialOptions {
    // Fields of InitialOptions
}

The #[serde(rename = "INITIAL_OPTIONS")] attribute tells Serde to use the specified string ("INITIAL_OPTIONS" in this case) as the JSON key when serializing and deserializing the initial_options field.Using Clap, how can I give an argument a short name d and the long name crawl_day?In Clap, you can give an argument both a short and a long name by using the short and long methods when defining the argument. Here's an example of how to do this:

use clap::{App, Arg};

fn main() {
    let matches = App::new("My App")
        .arg(
            Arg::new("crawl_day")
                .short('d')
                .long("crawl_day")
                .value_name("CRAWL_DAY")
                .about("Specify the crawl day")
                .takes_value(true),
        )
        .get_matches();

    // You can access the value of the argument like this:
    if let Some(crawl_day) = matches.value_of("crawl_day") {
        println!("How would I do that with `Cli::parse()` instead?To use `clap` with a struct-based approach and `Cli::parse()`, you'll need to use the `clap_derive` crate to derive the `Clap` trait for your struct. Here's an example:

1. Add `clap_derive` to your `Cargo.toml`:

```toml
[dependencies]
clap = "3.0"
clap_derive = "3.0"
  1. Define the struct with the appropriate attributes for the short and long names:
use clap::Clap;

#[derive(Clap, Debug)]
#[clap(name = "My App", version = "1.0", author = "Your Name")]
struct Cli {
    /// Specify the crawl day
    #[clap(short = 'd', long = "crawl_day")]
    crawl_day: String,
}

fn main() {
    let cli = Cli::parse();

    // Access the crawl_day field like this:
    println!("Crawl day: {}", cli.crawl_day);
}

In this example, the #[clap(short = 'd', long = "crawl_day")] attribute sets the short and long names for the crawl_day field. When you run your application, you can use either -d or --crawl_day to provide a value for this argument.
