Envconfig

An easy way to build a config structure form environment variables in Rust.

Usage

Let's say you application relies on the following environment variables:

• DB_HOST
• DB_PORT

And you want to initialize Config structure like this one:

rs struct Config { host: String, port: u16 }

You can achieve this with the following code without boilerplate:

```rs

[macro_use] extern crate envconfig;

envconfig!(Config { dbhost: String = "DBHOST", dbport: u16 = "DBPORT" });

let config = Config::initordie(); ```

Running tests

To prevent flaky tests run them in one thread:

cargo test -- --test-threads=1
