//! `Mingling` Example - General Renderer
//!
//! ## Step1 - Enable Feature
//! Enable the `general_renderer` feature for mingling in `Cargo.toml`
//! ```toml
//! [dependencies]
//! mingling = { version = "...", features = ["general_renderer", "parser"] }
//! ```
//!
//! ## Step2 - Add Dependencies
//! Add `serde` dependency to `Cargo.toml` for serialization support
//! ```toml
//! [dependencies]
//! serde = { version = "1", features = ["derive"] }
//! ```
//!
//! ## Step3 - Write Code
//! Write the following content into `main.rs`
//!
//! ## Step3 - Build and Run
//! ```bash
//! cargo run --manifest-path ./examples/example-general-renderer/Cargo.toml -- render Bob 22
//! cargo run --manifest-path ./examples/example-general-renderer/Cargo.toml -- render Bob 22 --json
//! cargo run --manifest-path ./examples/example-general-renderer/Cargo.toml -- render Bob 22 --yaml
//! ```
//!
//! Will print:
//! ```plain
//! Bob is 22 years old
//! {"member_name":"Bob","member_age":22}
//! member_name: Bob
//! member_age: 22
//! ```
