1/// This crate defines an attribute macro `#[settings(key = "xxx")]` to define settings to be
2/// initialized when they are used.
3/// 
4/// Example:
5///
6/// ```rust
7/// use lazy_settings::settings;
8///
9/// #[settings(key = "abcde")]
10/// struct AbcdeSettings {
11///   pub field_1: String,
12/// }
13/// ```
14///
15/// This will implement a `get(instance_name: &str)` method for `AbcdeSettings`, when `get(...)` is called, the settings
16/// will be returned if it's initialized before. Otherwise the
17/// fields are read from the environment variables in the following format. (Note that `abcde` is the key specified in the macro.)
18///
19/// `ALULU_APP_ABCDE_{instance_name.uppercase()}_{}` environment variables, where `{}` is the field names in upper case.
