# EnvOption

[![crates.io](https://img.shields.io/crates/v/envoption.svg)](https://crates.io/crates/envoption)

Simple functions for parsing environment variables when reading config.

* `require` - Parse an environment variable or return an error if it doesn't exist.

* `optional` - Same as above, but return an `Option` set to `None` if the variable doesn't exist.

* `with_default` - As above, but return a default value if the variable doesn't exist.
