Figment   ![ci.svg] ![crates.io] ![docs.rs]

Figment is a semi-hierarchical configuration library for Rust so con-free, it's unreal.

```rust use serde::Deserialize;

use figment::{Figment, providers::{Format, Toml, Json, Env}};

[derive(Deserialize)]

struct Package { name: String, authors: Vec, publish: Option, // ... and so on ... }

[derive(Deserialize)]

struct Config { package: Package, rustc: Option, // ... and so on ... }

let config: Config = Figment::new() .merge(Toml::file("Cargo.toml")) .merge(Env::prefixed("CARGO_")) .merge(Env::raw().only(&["RUSTC", "RUSTDOC"])) .join(Json::file("Cargo.json")) .extract()?; ```

See the documentation for a detailed usage guide and information.

Usage

Add the following to your Cargo.toml, enabling the desired built-in providers:
