Cloud Foundry Environment

A small library to get you going in no 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

[dependencies]
cf-env = "0.1.7"

After that, just check what you need and get it, you may wanna check out the docs.rs page. For example CF_INSTANCE_INDEX

let instance_index = cf_env::get_instance_index().unwrap();

Or for example if you need to get some credentials:

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 = cf_env::get_service_by_name::<CustomCredentials>("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

use serde_json::Value;
use cf_env::Service;

let service: Service<Value> = cf_env::get_service_by_name("my_db").unwrap();

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