a0

A Rust procedural macro for automatically generating structs from configuration files (JSON, YAML, TOML).

Example Usage

1. Create a configuration file (e.g., config.yaml).
2. Use the generate attribute macro:

server:
  port: 8080
features:
  - logging
  - authentication

Generate and use the struct:

#[generate("config.yaml")]
struct AppConfig;

fn main() {
    let config = AppConfig::new();
    println!("Server port: {}", config.server.port);
    println!("Features: {:?}", config.features);
}

API

• new(): Creates a new instance with values from the file.
• default(): Creates a new instance no values from the file.
• is_empty(): Returns true if all fields are default values.
