Usage

use json_schema_ast::{build_and_resolve_schema, SchemaNode};
use json_schema_fuzz::generate_value;
use serde_json::json;
use rand::thread_rng;

let raw = json!({
    "type": "object",
    "properties": {
        "flag": { "type": "boolean" },
        "count": { "type": "integer" }
    },
    "required": ["flag"]
});

// Build AST
let schema_node: SchemaNode = build_and_resolve_schema(&raw).unwrap();

// Generate a random value
let mut rng = thread_rng();
let value = generate_value(&schema_node, &mut rng, 4);

println!("{}", value);
