serde_kson Macro

serde_kson is a Rust macro that simplifies the process of building and managing JSON-like data structures. It allows you to dynamically create and manipulate nested JSON objects and arrays using a simple and intuitive syntax.

Features

• Easily create nested JSON structures.
• Supports both object and array syntax.
• Convenient access and update operations.
• Built on top of serde_json for seamless integration.

Dependencies

To use serde_kson, make sure your Cargo.toml includes the following dependencies:

[dependencies]
serde_json = "1.0"
serde_kson = "0.2.1"

Example Usage

Here is how you can use the kson! macro to build and interact with a JSON-like structure in Rust:

use serde_kson::kson; // Import the kson macro

fn main() {
    // Create a new JSON-like structure
    kson!(a);
    
    // Set values for the JSON object
    kson!(a["name"] = "kinggunil");
    kson!(a["age"] = 40);
    kson!(a["phone"]["office"] = "010-28**-3440");
    kson!(a["phone"]["home"] = "031-7**-2440");
    kson!(a["country"][0] = "Korea");
    kson!(a["country"][1] = "Canada");
    kson!(a["like"]["number"] = 777);
    kson!(a["like"]["numbers"][0]["a"] = 777777);
    kson!(a["like"]["numbers"][1]["b"] = 121212);

    println!("{:#?}",a);
    // Output:
    /*
    Object {
        "age": Number(40),
        "country": Array [
            String("Korea"),
            String("Canada"),
        ],
        "like": Object {
            "number": Number(777),
            "numbers": Array [
                Object {
                    "a": Number(777777),
                },
                Object {
                    "b": Number(121212),
                },
            ],
        },
        "name": String("kinggunil"),
        "phone": Object {
            "home": String("031-7**-2440"),
            "office": String("010-28**-3440"),
        },
    }    
     */

    // Access and print the values
    println!("Name: {:?}", kson!(a["name"] : String)); // Output: "kinggunil"
    println!("Age next year: {:?}", kson!(a["age"] : i64) + 1); // Output: 41
    println!("Office phone: {:?}", kson!(a["phone"]["office"] : String)); // Output: "010-28**-3440"
    println!("Home phone: {:?}", kson!(a["phone"]["home"] : String)); // Output: "031-7**-2440"
    println!("First country: {:?}", kson!(a["country"][0] : String)); // Output: "Korea"
    println!("Second country: {:?}", kson!(a["country"][1] : String)); // Output: "Canada"
    println!("number: {:?}", kson!(a["like"]["number"] : i64)); // Output: 777
    println!("number: {:?}", kson!(a["like"]["numbers"][0]["a"] : i64)); // Output: 777
    println!("number: {:?}", kson!(a["like"]["numbers"][1]["b"] : i64)); // Output: 121212
