llm-toolkit 0.63.1

//! Example demonstrating the use of external template files with the ToPrompt derive macro.
//!
//! This example shows how to:
//! - Load templates from external files using `template_file`
//! - Enable template validation with the `validate` flag
//! - Use Jinja2 syntax in external templates
//!
//! Note: Template files are located in `examples/templates/` directory.
