Trait AsEnvTypeStr 

pub trait AsEnvTypeStr {
    // Required method
    fn as_env_type_str(&self) -> Option<String>;
}

AsEnvTypeStr is a trait that covert some type to a string, which is the environment type. This trait can extend the existing configuration struct to get the environment type.

Example

use env_type::types::{EnvType, AsEnvTypeStr};

struct Config {
   env_str: String,
}

impl AsEnvTypeStr for Config {
  fn as_env_type_str(&self) -> Option<String> {
     Some(self.env_str.clone())
 }
}
let config = Config {
  env_str: "dev".to_string(),
};
assert_eq!("dev", config.as_env_type_str().unwrap());

Required Methods

fn as_env_type_str(&self) -> Option<String>
