This crate contains a macro for generating a struct which reads the environmental variables defined in the configured file.

This allows to have a single point of definition for the env configuration, thus avoiding a possible incoherence between the documentation and the implementation.

Note: I'm the developer of this crate, I'm sharing this hoping that it could help someone

If the spec contains default values why not make a constructor with all the missing fields or implement Default when all fields are covered?

Also lol:

#[test]
fn test_config_load() {
    todo!();
}

    For the first implementation I wanted to keep it simple, I don't exclude that in the future it will change.

    Also lol:

    Yep, I still need to figure out deep macro testing, for now I use the integration tests and cargo expand. This will absolutely change in the future :)

    Thanks for the feedback!
