Usage

Load Service Account

There are two ways to instantiate a service account.

1. Point to a file

let service_account = gauthenticator::ServiceAccountKey::from_file("./path-to/service-account-key.json").unwrap();

2. Using the GOOGLE_APPLICATION_CREDENTIALS environment variable

let service_account = gauthenticator::ServiceAccountKey::from_env().unwrap();

Get Access Token

let service_account = gauthenticator::ServiceAccountKey::from_env().unwrap();
let token = service_account.access_token(None)?;
