Crates designed to combine templates with data to produce documents, usually with an emphasis on processing text.

Rust Crates for Template Engines

This table lists popular Rust template engines and categorizes them by their approach and features.

Template EngineDescriptionKey FeaturesCrate Name
String-based Templating (Simple)Focuses on string interpolation and simple logic within templates.Easy to learn, good for basic templating.minijinja⮳, tera⮳ (can also be used for more advanced cases)
String-based Templating (Advanced)Offers more advanced features like control flow, loops, and expressions.More powerful, but can be more complex.tera⮳, handlebars⮳
Type-safe TemplatingLeverages Rust's type system for compile-time checking of templates.Improved safety and reduced runtime errors.askama⮳, maud⮳
HTML TemplatingSpecifically designed for generating HTML.Often includes features like HTML escaping and code formatting.maud⮳, yew⮳ (components can act like templates), perseus⮳ (for static site generation)
Markup Templating (General)Can be used for various markup languages (HTML, XML, etc.).Flexible and extensible.markup⮳
Logic-less TemplatingEmphasizes separation of concerns by minimizing logic within templates.Cleaner templates, often used with more complex logic handled in Rust code.handlebars⮳, minijinja⮳ (can be used in a logic-less way)
High-Performance TemplatingOptimized for speed and efficiency.Suitable for applications where performance is critical.minijinja⮳, tera⮳ (benchmarks show good performance)
Compile-time TemplatingTemplates are processed at compile time, reducing runtime overhead.Faster rendering, but requires recompilation for template changes.askama⮳, maud⮳

Crate Details

  • minijinja⮳: A lightweight and fast templating engine inspired by Jinja2. Good balance of features and performance. Suitable for both simple and more complex scenarios.
  • tera⮳: A powerful and flexible templating engine with support for various features, including custom functions and filters. Can be used for both simple and advanced templating needs.
  • handlebars⮳: A logic-less templating engine inspired by Handlebars.js. Good for separating presentation from logic.
  • askama⮳: A type-safe and compile-time templating engine. Provides excellent compile-time error checking. Good for applications where safety and performance are critical.
  • maud⮳: A fast and type-safe HTML templating engine that generates HTML at compile time. Excellent for web development.
  • markup⮳: A general-purpose markup templating engine. Can be used for various markup languages.
  • yew⮳: A front-end framework for building web apps with Rust. Components can be used like templates.
  • perseus⮳: A static site generator that uses templates.

Choosing a Template Engine

The best template engine for your project depends on your specific requirements:

  • Simplicity: For basic templating, minijinja⮳ is a good choice.
  • Power and Flexibility: tera⮳ offers a wide range of features.
  • Type Safety: askama⮳ and maud⮳ provide compile-time checking.
  • Performance: minijinja⮳, tera⮳, askama⮳, and maud⮳ are all performant.
  • HTML Generation: maud⮳ and yew⮳ are well-suited for HTML templating.
  • Logic-less Templating: handlebars⮳ and minijinja⮳ (used in a certain way) are good choices.
