Handlebars-Sprig

Handlebars-Sprig是将Sprig模板函数移植到Rust编程语言的实现，同时支持Rust的Handlebars库。

它并不旨在与Sprig完全兼容。Go模板和Go语法可能在Handlebars和Rust中感觉不太合适。但Handlebars-Sprig的目标是足够接近，使其感觉熟悉。

Handlebars-Sprig最初是为Bartholomew Micro-CMS开发的，并且目前正在该系统中使用。

使用方法

在您的Rust代码中，您需要注册handlebars助手函数

use handlebars::Handlebars;
use handlebars_sprig;

fn main() {
    // Get a handlebars instance
    let mut hbs = Handlebars::new();

    // THE IMPORTANT PART: Add the helpers
    handlebars_sprig::addhelpers(&mut hbs);

    // From this point, you can do whatever you want to do with the
    // handlebars instance. It will have all of the functions available
    // to the templates.
    let tpl = "{{ add 1 2 }}";

    // Example of running a template render.
    let empty_context: Vec<String> = vec![];
    println!("Template produced: {}", hbs.render_template(tpl, &empty_context).unwrap())
}

上面的代码产生以下输出

$ cargo run --example basic
    Finished dev [unoptimized + debuginfo] target(s) in 0.05s
     Running `target/debug/examples/basic`
Template produced: 3
