formars-derive

Opt-in #[derive(FormSchema)] companion for [formars-core]: derives a companion schema type from a plain named-field struct — nested composition, renames, skips, metadata slots, and builder overrides via a small closed #[form(..)] attribute grammar.

use formars_core::prelude::*;
use formars_derive::FormSchema;

#[derive(FormSchema)]
struct Signup {
    #[form(label = "Email")]
    email: String,
    age: u32,
}

let issues = SignupSchema::new()
    .validate_value(&Value::from("not-an-object"));

The macro executes on the host compiler only — wasm consumers pay nothing extra. See the repository and the formars facade for the full toolkit.
