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=""
