deep-diff

A small Rust crate to deeply diff serde_json::Value trees.

This crate helps you compare two JSON values recursively and returns a list of differences, showing exactly which parts have changed.

Features

• Compare JSON objects, arrays, strings, numbers, booleans, and nulls
• Reports differences with precise JSON path notation
• Lightweight and easy to integrate

Usage

Add this to your Cargo.toml:

[dependencies]
deep-diff = "0.1"
serde_json = "1.0"

Example

use deep_diff::{deep_diff, Difference};
use serde_json::json;

fn main() {
    let a = json!({"name": "Alice", "age": 30});
    let b = json!({"name": "Bob", "age": 30});

    let diffs = deep_diff(&a, &b);

    for diff in diffs {
        println!("Changed at path '{}': from {:?} to {:?}", diff.path, diff.before, diff.after);
    }
}
