Rust template engine benchmarks

This repo tries to assess Rust template engine performance. Following the download ratings from crates.io, these nine projects are assessed:

write!: the std library write! macro
Handlebars: Handlebars templating implemented in Rust
Tera: template engine based on Jinja2/Django templates
Liquid: the liquid templating language for Rust
Askama: type-safe, compiled Jinja-like templates for Rust
horrorshow: a templating library written in rust macros
ructe: Rust Compiled Templates, efficient type-safe web page templates
fomat: alternative syntax for print/write/format-like macros with a small templating language
markup: A blazing fast, type-safe template engine for Rust.
maud: A Compile-time HTML template engine for Rust.
sailfish: Simple, small, and extremely fast template engine for Rust
rusty-html: Rusty HTML is a html-templating framework

Results

These results are from 2023-4-25 (rustc 1.70.0), running on an MacBook Pro 16 (2021) M1 Max CPU. Your mileage may vary.
