Rod Derive

Crates.io Documentation

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 enumerations based on declarative attributes.

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

Usage

Add Rod Validation to your Cargo.toml:

[dependencies]
rod_validation = "0.2.2"

The derive macro is available through the prelude:

use rod_validation::prelude::*;

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