Env-Inventory: Environment Variable Management

env-inventory is a Rust library designed to manage and consolidate the process of fetching parameters from the environment. It offers a flexible system to work with environment variables and configurations stored in TOML files.

Features

• 🌍 Unified Access: Streamline the way parameters are fetched from the environment.
• 📁 TOML Support: Read and merge configurations directly from TOML files, allowing hierarchical configurations.
• ✅ Validation: Validate and ensure that required environment variables are set.

Getting Started

Installation

Add env-inventory to your Cargo.toml:

[dependencies]
env-inventory = "0.1.0" # Check crates.io for the latest version

Usage

1. Define required environment variables using the RequiredVar struct.

inventory::submit!(RequiredVar::new("DATABASE_URL", None));

2. Load and validate environment variables from your TOML configurations:

let paths = ["path/to/settings.toml"];
env_inventory::load_and_validate_env_vars(&paths, "env").unwrap();

Error Handling

The library provides an EnvInventoryError enum to handle various error types such as:

• Reading or parsing the settings file.
• Missing required environment variables.

Testing

We provide a suite of tests to validate core functionalities. Run tests with:

cargo test
