Crate cf_env

Easy and typed abstraction on Cloud Foundry Environment variables

It allows you to get:

• Services, optionally filtered by name or type
• Application infos
• Cloud Foundry app instance set variables, most of the times starting with CF_

It’s meant to get you away from boilerplating and get you started with typed variables while keeping simplicity
