JSON to Rust Struct.
Generate Rust structs with serde annotations from a bounded JSON sample.
How to use JSON to Rust Struct
Paste source text, adjust the available settings and generate. Review the output before integrating it into a project.
How it works
Generate Rust structs with serde annotations from a bounded JSON sample. Root must be an object. Mixed or empty arrays use generic values; null uses a generic nullable type. Review generated models and add project-specific constraints. Source is processed locally; generated code is not executed.
Example
Generate the included sample to inspect the output.
