Module nanoservices_utils::config

Defines extracting config variables based on the method to enable testing as well as production use. A good is API views. Wehn when defining an API view function, we can use the GetConfigVariable trait to to enable config variables from different sources be applied to the API view function by having the following outline:

use nanoservices_utils::config::GetConfigVariable;
 
pub async fn api_view<T: GetConfigVariable>() {
}

Anything passed into the api_view function will be able to get config variables from the source defined by the type of the generic parameter T. For example, if we want to get config variables from the environment, we can pass the EnvConfig struct as api_view::<EnvConfig>(). However, we can implement the GetConfigVariable on a random struct for unit testing and pass that struct into the api_view function for testing. use nanoservices_utils::config::GetConfigVariable;

Structs

• EnvConfig
  Defines the struct for getting config variables from the environment

Traits

• GetConfigVariable
  Used for extracting config cariables.
