base on Type-safe, compiled Jinja-like templates for Rust # Askama [](https://docs.rs/askama/) [](https://crates.io/crates/askama) [](https://github.com/djc/askama/actions?query=workflow%3ACI) [](https://discord.gg/ZucwjE6bmT) Askama implements a template rendering engine based on [Jinja](https://jinja.palletsprojects.com/). It generates Rust code from your templates at compile time based on a user-defined `struct` to hold the template's context. See below for an example, or read [the book][docs]. **"Pretty exciting. I would love to use this already."** -- [Armin Ronacher][mitsuhiko], creator of Jinja All feedback welcome. Feel free to file bugs, requests for documentation and any other feedback to the [issue tracker][issues] or [tweet me][twitter]. Askama was created by and is maintained by Dirkjan Ochtman. If you are in a position to support ongoing maintenance and further development or use it in a for-profit context, please consider supporting my open source work on [Patreon][patreon]. ### Feature highlights * Construct templates using a familiar, easy-to-use syntax * Benefit from the safety provided by Rust's type system * Template code is compiled into your crate for [optimal performance][benchmarks] * Optional built-in support for Actix, Axum, Rocket, and warp web frameworks * Debugging features to assist you in template development * Templates must be valid UTF-8 and produce UTF-8 when rendered * IDE support available in [JetBrains products](https://plugins.jetbrains.com/plugin/16591-askama-template-support) * Works on stable Rust ### Supported in templates * Template inheritance * Loops, if/else statements and include support * Macro support * Variables (no mutability allowed) * Some built-in filters, and the ability to use your own * Whitespace suppressing with '-' markers * Opt-out HTML escaping * Syntax customization [docs]: https://djc.github.io/askama/ [fafhrd91]: https://github.com/fafhrd91 [mitsuhiko]: http://lucumr.pocoo.org/ [issues]: https://github.com/djc/askama/issues [twitter]: https://twitter.com/djco/ [patreon]: https://www.patreon.com/dochtman [benchmarks]: https://github.com/djc/template-benchmarks-rs How to get started ------------------ First, add the Askama dependency to your crate's `Cargo.toml`: ```sh cargo add askama ``` Now create a directory called `templates` in your crate root. In it, create a file called `hello.html`, containing the following: ``` Hello, {{ name }}! ``` In any Rust file inside your crate, add the following: ```rust use askama::Template; // bring trait in scope #[derive(Template)] // this will generate the code... #[template(path = "hello.html")] // using the template in this path, relative // to the `templates` dir in the crate root struct HelloTemplate<'a> { // the name of the struct can be anything name: &'a str, // the field name should match the variable name // in your template } fn main() { let hello = HelloTemplate { name: "world" }; // instantiate your struct println!("{}", hello.render().unwrap()); // then render it. } ``` You should now be able to compile and run this code. Review the [test cases] for more examples.
