json: Data Serialization

The json module allows you to parse and generate JSON data, making it easy to build APIs or save configuration files.

Parsing JSON

You can parse a JSON string into a JsonValue variant. 

import json



var raw = """{"name": "Alice", "age": 25}"""

var result = json::parse(raw)



var Object(map) = result else return



var name = map.get("name").as_string()

var age = map.get("age").as_int()

Generating JSON

Use the JsonBuilder to construct JSON structures programmatically. 

var builder = json::JsonBuilder()

builder.begin_object()

    builder.put_string("status", "success")

    builder.put_int("code", 200)

    

    builder.begin_array("data")

        builder.put_int(1)

        builder.put_int(2)

        builder.put_int(3)

    builder.end_array()

builder.end_object()



var output = builder.to_string()

// {"status":"success","code":200,"data":[1,2,3]}
