CF Env library

A small library to get you going in not time with typed environment variables for you Cloud Foundry envirnoment.

Goals: - Remove boilerplate code for projects using cf - Use the power of rust to get the environment variables in a typed way - Give you the flexiblity to define custom values such as credential structures to meet your needs

Usage

Getting this crate is easy as adding it to your dependencies toml [dependencies] cf-env = "0.0.1"

After that, just check what you need and get it, you may wanna check out the docs.rs page. For example CF_INSTANCE_INDEX rust let instance_index = cf_env::get_instance_index().unwrap();

Or for example if you need to get some credentials: ```rust use serde::{Serialize, Deserialize};

[derive(Serialize, Deserialize)]

pub struct CustomCredentials { pub password: String, pub username: String, pub host: String, pub port: u16, }

// After that you can use it let service = cfenv::getservicebyname::("my_db").unwrap(); ```

There is no need for typed credentials if you would like to parse it anyway and then deal with the Value enum from serde_json ```rust use serdejson::Value; use cfenv::Service;

let service: Service = cfenv::getservicebyname("my_db").unwrap();

let uri = service.credentials["uri"].as_str().unwrap(); ```

FYI, some tests have been written, more to follow in the next few days, tough everything should work
