+//! Example structural renderer
+//!
+//! > This example demonstrates how to use the `structural_renderer` feature to render data into structures such as json / yaml
+//!
+//! Run
+//! ```bash
+//! cargo run --manifest-path examples/example-structural-renderer/Cargo.toml --quiet -- render Bob 22
+//! cargo run --manifest-path examples/example-structural-renderer/Cargo.toml --quiet -- render Bob 22 --json
+//! cargo run --manifest-path examples/example-structural-renderer/Cargo.toml --quiet -- render Bob 22 --yaml
+//! ```
+//!
+//! Output:
+//! ```plain
+//! Bob is 22 years old
+//! {"member_name":"Bob","member_age":22}
+//! member_name: Bob
+//! member_age: 22
+//! ```
