Rod Derive

Procedural macro for the Rod validation library. This crate provides the #[derive(RodValidate)] macro that generates validation code based on field attributes.

Overview

rod_derive is the procedural macro component of the Rod validation framework. It automatically generates validation implementations for structs and enums based on declarative attributes.

This crate is typically used through the main rod crate and not directly.

Usage

Add Rod to your Cargo.toml:

[dependencies]

rod = "0.2.0"

The derive macro is available through the prelude:

use rod::prelude::*;

#[derive(RodValidate)]
struct User {
    #[rod(String {
        length: 3..=50,
        format: Email,
    })]
    email: String,
}
