Configr

The dead easy way to use config files in your project

This will load a config.toml file if it exists, otherwise it will create the needed folders and the toml file.
It can either use the OS config directories which are as follows

• Linux: $XDG_CONFIG_HOME/app-name/config.toml
• Windows: %APPDATA%/app-name/config.toml
• Mac OS: $HOME/Library/Application Support/app-name/config.toml

or a custom config directory

Usage

Add the following to your Cargo.toml

configr = "0.7.0"

or use cargo-edit with cargo add configr

then in your project add the following snippet

use configr::{Config, ConfigrDefault};
#[derive(ConfigrDefault, Deserialize, Serialize, Default)]
pub struct BotConfig {
    bot_username: String,
    client_id: String,
    client_secret: String,
    channel: String,
}

replacing BotConfig with your configuration struct

and then load you can load the config, usually at the start of the application with the load function to load from the system config directory

let config = BotConfig::load("bot app", true).unwrap(); // Will load from /home/USER/.config/bot-app/config.toml

or with the load_with_dir function to use a custom config directory

let config = BotConfig::load_with_dir("bot app", "$HOME").unwrap(); // Will load from /home/USER/bot-app/config.toml

Use ConfigrDefault if you want the config.toml to be populated with default values, based on Default implentation, or use Configr if you want it to be populated with empty fields with the correct names

Example of above BotConfig
With Configr

bot_username=
client_id=
client_secret=
channel=

and with ConfigrDefault

bot_username=""
client_id=""
client_secret=""
channel=""
