 /// # Arguments

-/// Given a Struct:
-///
-/// ```rust
-/// pub struct CmdOptions {
-///     pub endpoint: String,
-///     pub log_level: Option<String>,
-/// }
-/// ```
-///
-/// The `ConfigSource` derive macro will implement `config::Source`:
-///
-/// ```rust
-/// impl config::Source for CmdOptions {
-///     fn clone_into_box(&self) -> Box<dyn config::Source + Send + Sync> {
-///         Box::new((*self).clone())
-///     }
-///
-///     fn collect(&self) -> Result<config::Map<String, config::Value>, config::ConfigError> {
-///         let mut entries: config::Map::<String, Option<config::Value>> = config::Map::from([
-///             (
-///                 String::from("endpoint"),
-///                 (&self.endpoint).clone().map(|v| config::Value::from(v))
-///             ),
-///             (
-///                 String::from("log_level"),
-///                 Some(config::Value::from((&self.log_level).clone()))
-///             ),
-///         ]);
-///
-///         entries.retain(|_, v| v.is_some());
-///         let entries_w_values = entries.clone();
-///         let valid_entries: config::Map::<String, config::Value> = entries_w_values.iter().map(|(k, v)| (k.clone(), v.clone().unwrap())).collect();
-///
-///         Ok(valid_entries.clone())
-///     }
-/// }
-/// ```
-///
-/// This allows for Structs to be used as a `Source` for configuration through the `config` crate.
