Structural JSON Diff Library for Rust

sjdiff – is a library for Rust that compares two JSON values and produces a structural difference between them.

Features

• Compare any JSON value.
• Ignore JSON paths so they are not included in the result diff.
• Customize the equation logic, e.g. null == [], 0.111 == 0.11, 2023-07-25T15:30:01Z == 2023-07-25T15:30:00Z.

Example

Compare two objects:

fn main() {
    let obj1 = serde_json::json!({
        "user": "John",
        "age": 31
    });

    let obj2 = serde_json::json!({
        "user": "John",
        "age": 33
    });

    let diff = sjdiff::DiffBuilder::default()
        .source(obj1)
        .target(obj2)
        .build()
        .unwrap();
    let diff = diff.compare();

    serde_json::to_writer_pretty(std::io::stdout(), &diff).unwrap();
}

See more in the examples.
