# env_vars_explorer

This crate provides a simple macro that can be used to explore what environment variables are
available at compile-time in your rust project.

Simply run `env_vars_explorer::explore!` anywhere and all environment variables will be printed
from the proc macro. This is useful to discover what environment variables are available at
compile-time v.s. at runtime.

```rust
env_vars_explorer::explore!();
```
