config-rs

a simple tool to adapt different configuration file format

plan

• intergrate with toml, yaml, json. ...

usage

First, we need to add serde and xcfg to our Cargo.toml:

cargo add serde -F derive
cargo add xcfg -F full

Then, we can use XCfg to load configuration from different file formats:

use serde::{Deserialize, Serialize};
use xcfg::XCfg;

#[derive(Debug, Serialize, Deserialize, XCfg)]
struct Config {
    name: String,
    age: u32,
}

fn main() {
    let config = Config::load("config")
        .expect("Failed to load config.[toml|yaml|yml|json]")
        .into_inner();
    println!("{:?}", config);
}

This example is also available in the example directory. You can clone this repo and run the example:

cd example && cargo r --example full --features full
