-//! Example on how the `rename_all` parameter works.
-//!
-//! `rename_all` can be used to override the casing style used during argument
-//! generation. By default the `kebab-case` style will be used but there are a wide
-//! variety of other styles available.
-//!
-//! ## Supported styles overview:
-//!
-//! - **Camel Case**: Indicate word boundaries with uppercase letter, excluding
-//!                   the first word.
-//! - **Kebab Case**: Keep all letters lowercase and indicate word boundaries
-//!                   with hyphens.
-//! - **Pascal Case**: Indicate word boundaries with uppercase letter,
-//!                    including the first word.
-//! - **Screaming Snake Case**: Keep all letters uppercase and indicate word
-//!                             boundaries with underscores.
-//! - **Snake Case**: Keep all letters lowercase and indicate word boundaries
-//!                   with underscores.
-//! - **Verbatim**: Use the original attribute name defined in the code.
