Deserialization converts data-format representations into Rust values. Serde supplies the generic Deserialize trait, while serde_json connects that model to JSON. section 6.3
Parsing and using JSON data
A parsed Data value can feed ordinary Rust logic: summing the name length and numeric value produces 948146 for the sample input, matching a Python implementation.
