config-file2

Extremely easy to load and store your configuration file!

Usage

1. Add dependency:

   cargo add config-file2
   

2. Enable which format you want to use in features.
   • all
   • toml (enabled by default)
   • json
   • xml
   • yaml
   • ron

Here's an example of how to use it with json and yaml format:

[dependencies]
config-file2 = { version = "0.4", features = ["json", "yaml"] }

Examples

use config_file2::{LoadConfigFile, StoreConfigFile};
use serde::{Serialize, Deserialize};

#[derive(Serialize, Deserialize)]
struct Config {
    host: String,
}

// store
Config { host: "example.com".into() }.store("/tmp/myconfig.toml").unwrap();

// load
let config = Config::load("/tmp/myconfig.toml").unwrap().unwrap();
assert_eq!(config.host.as_str(), "example.com");

Another way to store a struct into a configuration file:

use config_file2::Storable;
use serde::{Serialize, Deserialize};
use std::path::{Path, PathBuf};

#[derive(Serialize)]
struct TestStorable {
    path: PathBuf,
}

impl Storable for TestStorable {
    fn path(&self) -> &Path {
        &self.path
    }
}

TestStorable { path: PathBuf::from("/tmp/myconfig.toml") }.store().unwrap();
