Rydantic derive

Procedural macros for Rydantic, a Rust library for data modeling, validation, JSON Schema and native Cap'n Proto.

Use the rydantic crate, which enables and re-exports #[derive(Model)] by default:

[dependencies]
rydantic = "0.2.0"

use rydantic::Model;

#[derive(Debug, Model)]
struct User {
    #[model(trim, min_length = 2)]
    name: String,
    #[model(ge = 18, le = 120)]
    age: u8,
}

let user = User::parse_json(r#"{"name":" Alice ","age":25}"#)?;
assert_eq!(user.name, "Alice");
# Ok::<(), rydantic::ValidationErrors>(())

See the API documentation and complete guide for borrowing, validators, model attributes, schemas and Cap'n Proto mappings.
