markup.rs

A blazing fast, type-safe template engine for Rust.

markup.rs is a template engine for Rust powered by procedural macros which parses the template at compile time and generates optimal Rust code to render the template at run time. The templates may embed Rust code which is type checked by the Rust compiler enabling full type-safety.

Features

Fully type-safe with inline highlighted errors when using editor extensions like rust-analyzer.
Less error-prone and terse syntax inspired by Haml, Slim, and Pug.
Zero unsafe code.
Zero runtime dependencies.
⚡ Blazing fast. The fastest in this benchmark among the ones which do not use unsafe code, the second fastest overall.

Example

markup::define! {
    Home<'a>(title: &'a str) {
        @markup::doctype()
        html {
            head {
                title { @title }
                style {
                    "body { background: #fafbfc; }"
                    "#main { padding: 2rem; }"
                }
            }
            body {
                @Header { title }
                #main {
                    p {
                        "This domain is for use in illustrative examples in documents. You may \
                        use this domain in literature without prior coordination or asking for \
                        permission."
                    }
                    p {
                        a[href = "https://www.iana.org/domains/example"] {

                        }
                    }
                }
                @Footer { year: 2020 }
            }
        }
    }

    Header<'a>(title: &'a str) {
        header {
            h1 { @title }
        }
    }

    Footer(year: u32) {
        footer {
            "(c) " @year
        }

        "{}",
        Home {
            title: "Example Domain"

Output
