Maud: a compile-time template engine for Rust

html! {
    h1 { "Hello, world!" }
    p.intro {
        "This is an example of the "
        a href="" { "Maud" }
        " template language."

Maud is an HTML template engine for Rust. It's implemented as a macro, html!, which compiles your markup to specialized Rust code. This unique approach makes Maud templates blazing fast, super type-safe, and easy to deploy.

Why use Maud?

Tight integration with Rust

Since Maud is a Rust macro, it can borrow most of its features from the host language. Pattern matching and for loops work as they do in Rust. There is no need to derive JSON conversions, as your templates can work with Rust values directly.

Type safety

Your templates are checked by the compiler, just like the code around them. Any typos will be caught at compile time, not after your app has already started.

Minimal runtime

Since most of the work happens at compile time, the runtime footprint is small. The Maud runtime library, including integration with the Iron and Rocket web frameworks, is around 100 SLoC.

Simple deployment

There is no need to track separate template files, since all relevant code is linked into the final executable.

Why not use Maud?

Requires Nightly compiler

Maud uses unstable parts of the procedural macro API, and so you'll need to install the nightly version of Rust to use it.

Longer compile times

It can be inconvenient to iterate on a design, since every edit would trigger a recompile of the containing crate. With incremental compilation, though, the difference may not be as noticeable as you'd think.
