+//! Template struct for storing template strings and their parameters.
+//!
+//! The template supports two types of parameters:
+//! - Simple parameters: key-value pairs used to replace simple placeholders (`<<<key>>>` format) in the template.
+//! - Implementation parameters: for implementation blocks (`>>>>>>>>> block_name` and `@@@ >>> block_name` format),
+//!   can contain multiple parameter sets, each corresponding to an implementation instance.
+//!
+//! # Examples
+//! ```
+//! use just_template::Template;
+//!
+//! let mut tmpl = Template::from("Hello, <<<name>>>!".to_string());
+//! tmpl.insert_param("name".to_string(), "World".to_string());
+//! assert_eq!(tmpl.to_string(), "Hello, World!");
+//! ```
+//!
+//! Using the `tmpl_param!` macro makes it easier to add simple parameters:
+//! ```
+//! use just_template::{Template, tmpl_param};
+//!
+//! let mut tmpl = Template::from("<<<a>>> + <<<b>>> = <<<c>>>".to_string());
+//! tmpl_param!(tmpl, a = 1, b = 2, c = 3);
+//! assert_eq!(tmpl.to_string(), "1 + 2 = 3");
+//! ```
+//!
+//! Using the `tmpl!` macro adds implementation block parameters:
+//! ```
+//! use just_template::{Template, tmpl};
+//!
+//! let mut tmpl = Template::from("
+//! >>>>>>>>>> arms
+//! @@@ >>> arms
+//!     <<<crate_name>>> => Some(<<<crate_name>>>::exec(data, params).await),
+//! @@@ <<<
+//! ".trim().to_string());
+//! tmpl!(tmpl,
+//!     arms {
+//!         crate_name = "my",
+//!         crate_name = "you",
+//!     }
+//! );
+//! // Output the expanded template
+//! let expanded = tmpl.to_string();
+//! assert_eq!(expanded, "
+//!     my => Some(my::exec(data, params).await),
+//!     you => Some(you::exec(data, params).await),
+//! ".trim().to_string());
+//! ```
