// build up a group of 1000 (similar) people
let mut group = vec![
Team { idx: 0, name: "Jiangsu".into(), score: 43 },
Team { idx: 1, name: "Beijing".into(), score: 27 },
Team { idx: 2, name: "Guangzhou".into(), score: 22 },
Team { idx: 3, name: "Shandong".into(), score: 12 },
];
let mut data = Map::new();
data.insert("year".to_string(), to_json(&"2015".to_string()));
let mut handlebars = Handlebars::new();
handlebars
.register_template_string("table", template)
.unwrap();
b.iter(|| {
let mut data = data.clone();
data.insert("group".to_string(), to_json(&group));
handlebars.render("table", &data).unwrap()
});
}
In this template, I just need for loop index and input constant string
like {{"champion" | checkshow}} or move champion to ZapperEnv
But 1. ZapperEnv can't use filter function
But 2. the template can't input constant string,
So I modify struct "Team", add member called idx.
But I found only input string can output string.
So I modify {{p.idx | checkshow}} to {{p.name | checkshow}}
It's not work.
{{#each group as |p| ~}}
<li class=\"{{p.name | checkshow}}\">
<b>{{p.name}}</b>: {{p.score}}
</li>
{{/each~}}
// this part always get Error:"InvalidSyntax"
Why I do that?
To add zapper into this https://github.com/damody/template-benchmarks-rs
please fix zapper functional to run the benchmark.
