Template File templates/article.html

This page is rendered directly from an external HTML file located at 'templates/article.html'. Unlike inline macros, file-based templating enables UI designers and frontend developers to edit layout files without touching Rust source code or triggering Rust compiler recompilations.

// How Tera/Jinja2 template rendering works in Rullst:

let mut context = tera::Context::new();

context.insert("title", &"Decoupled MVC Architectures in Rust");

let html = tera.render("article.html", &context)?;

💡 Why File-Based Templates are Powerful

Developers coming from Django, Ruby on Rails, or Loco.rs often prefer keeping raw .html files in a dedicated templates/ directory. Rullst natively supports this workflow with zero ceremony, allowing full layout inheritance ({% extends "base.html" %}) and loop iterations.
