Rust Sample

This is the simple Rust project demonstrating how to work with concurrency, borrowing, pattern matching and error handling.

• The program reads file names passed as arguments which this was started with.
• Parse them into AST using external serde_json crate.
• Merge them into the one common JSON.
• Each file will be processed in the separate thread.

File handling:

1. accept only strings and nested objects as values.
2. flatten view of nested objects in the result.

Example

Input

Assume we have the following input files:

• file1.json {"name": "Artem"}
• file2.json {"second_name": "Ivanov", "passport": { "city": "Voronezh" }}
• file3.json {"status": "free"}

Execute

cargo run file1.json file2.json file3.json

Output

Prints common json: {"name": "Artem", "second_name": "Ivanov", "city": "Voronezh", "status": "free" }
