config_lite

A lightweight and customizable configuration management library for binary crates. Inspired by node config

Caveats

The values read from the configuration files must be owned, meaning they cannot be deserialized with serde into reference types

Still a work in progress

Example

Given the following json config file:

json { "foo": "bar", "test": { "user": { "id": 1, "name": "Foo Baz", "screen_name": "foo_baz", "isActive": true } }, "database": { "password": "{{DATABASE_PASSWORD}}" // config will read this value from the env var $DATABASE_PASSWORD } }

The configurations can be read like so:

```rust use config::Config; use serde::Deserialize;

[derive(Deserialize, Debug)]

struct User { id: u32, name: String, screenname: String, #[serde(rename(deserialize = "isActive"))] isactive: bool, }

let config = Config::new()?;

let value = config.get::("foo")?; let user = config.get::("test.user")?; let database_password = config.get::("database.password")?; ```
