field_names_derive

Introduction

A simple procedural macro for Rust that generates field name constants for structs. Perfect for when you need compile-time field names for serialization, validation, database mapping, or configuration.

Features

• ✅ Simple - No complex configuration, just #[derive(FieldNames)]
• ✅ IDE-friendly - Auto-generates helper modules for better IDE recognition
• ✅ Preserves naming - Constants match field names exactly (no case conversion)
• ✅ Compile-time constants - All field names available at compile time
• ✅ Helper methods - Includes field_names() and has_field() methods

Installation

Add to your Cargo.toml:

[dependencies]
field_names_derive = "0.1"

use field_names_derive::FieldNames;

#[derive(FieldNames)]
struct User {
    id: u64,
    name: String,
}

// User::id; // "id"

Run tests: cargo test -- --nocapture

Run example: cargo run --bin simple_fields
