Getenv.rs

🚧 We are building in public. This is presently under heavy construction.

✨ Features

• Implements a comprehensive set of environment variable getters for various platforms, programming languages, and tools.
• Provides a wide range of varsets (variable sets), including for: AWS, Cargo, Conda, CUDA, Docker, Git, Go, Homebrew, Java, Locale, macOS, NEAR, Node.js, OpenSSL, POSIX, Proxy, Python, Ruby, Rust, SSH, Windows, and XDG.
• Protects sensitive environment variables (such as API keys) by preventing their accidental copying, logging, or other exposure, and securely wiping them from memory when dropped.
• Treats empty environment variables the same as missing ones.
• Supports opting out of any feature using comprehensive feature flags.
• Adheres to the Rust API Guidelines in its naming conventions.
• 100% free and unencumbered public domain software.

🛠️ Prerequisites

• Rust 1.81+

⬇️ Installation

Installation via Cargo

cargo add getenv

Installation in Cargo.toml (with all features enabled)

[dependencies]
getenv = "0.1"

Installation in Cargo.toml (with only specific features enabled)

[dependencies]
getenv = { version = "0.1", default-features = false, features = ["posix"] }

👉 Examples

Importing the library

use getenv::*;

Reading environment variables

use getenv::aws::*;

println!("AWS_ACCESS_KEY_ID={:?}", aws_access_key_id());
println!("AWS_SECRET_ACCESS_KEY={:?}", aws_secret_access_key());
