Envie

Envie is a lightweight and user-friendly library for managing environment variables in Rust. It allows you to load and parse .env files effortlessly and provides type-safe access to environment variables for seamless integration into your applications.

Key Features

• Automatically loads .env files
• Retrieves environment variables by key
• Supports type-safe conversions (e.g., boolean, integers)
• Fallback to system environment variables

Installation

Add Envie to your Cargo.toml file:

envie = "0.1.0"

Then run:

cargo build

Usage

Here’s a quick example of how to use Envie:

Load environment variables

use envie::Envie;

fn main() {
let env = Envie::load().expect("Failed to load .env file");

    let database_url = env.get("DATABASE_URL").unwrap_or_else(|| "default_url".to_string());
    let debug_mode: bool = env.get_bool("DEBUG_MODE").unwrap_or(false);

    println!("Database URL: {}", database_url);
    println!("Debug Mode: {}", debug_mode);
}

Example .env file

DATABASE_URL=postgres://user:password@localhost:5432/mydb
DEBUG_MODE=true
