Trait for types that can retrieve their configuration key from environment variables

Required Associated Constants

const KEY_NAME: &'static str

The environment variable name for this client’s API key

Provided Methods

fn find_key() -> Option<String>

Find the API key by checking environment variables first, then .env file

fn find_key_with_user() -> String

Find the API key with user fallback - waits 15 seconds for user input then panics

fn prompt_save_to_env() -> bool

Prompt user if they want to save the API key to .env file Uses single keystroke detection with fallback to Enter

fn read_single_key() -> Result<String, Box<dyn Error>>

Attempt to read a single keystroke

fn save_to_env_file(api_key: &str) -> Result<(), Box<dyn Error>>

Save the API key to .env file

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
