Derive Macro Properties 

#[derive(Properties)]
{
    // Attributes available to this derive:
    #[prop]
}

Derive macro for automatically implementing properties parsing functionality.

This macro generates implementations for:

• from_file: Load properties from a file
• from: Create instance from a type that implements Into<HashMap<String, String>>
• default: Create instance with default values

Example

use props_util::Properties;
use std::io::Result;

#[derive(Properties, Debug)]
struct Config {
    #[prop(key = "server.host", default = "localhost")]
    host: String,
    #[prop(key = "server.port", default = "8080")]
    port: u16,
}

fn main() -> Result<()> {
    let config = Config::default()?;
    println!("Host: {}", config.host);
    println!("Port: {}", config.port);
    Ok(())
}
