This provides a [Handlebars](http://handlebarsjs.com/) `{{#switch}}` helper to

the already incredible [handlebars-rust](https://github.com/sunng87/handlebars-rust)

crate.

## Quick Start

You can easily add the ``{{#switch}}`` helper to a rust Handlebars object using

the `Handlebars#register_helper` method:

```rust

use handlebars::Handlebars;

use handlebars_switch::SwitchHelper;

let mut handlebars = Handlebars::new();

handlebars.register_helper("switch", Box::new(SwitchHelper));

```

### Example

Below is an example that renders a different page depending on the user's

access level:

```rust

extern crate handlebars_switch;

extern crate handlebars;

#[macro_use] extern crate serde_json;

use handlebars::Handlebars;

use handlebars_switch::SwitchHelper;

fn main() {

  let mut handlebars = Handlebars::new();

  handlebars.register_helper("switch", Box::new(SwitchHelper));

  let tpl = "\

      {{#switch access}}\

          {{#case \"admin\"}}Admin{{/case}}\

          {{#default}}User{{/default}}\

      {{/switch}}\

  ";

  assert_eq!(

      handlebars.template_render(tpl, &json!({"access": "admin"})).unwrap(),

      "Admin"

  );

  assert_eq!(

      handlebars.template_render(tpl, &json!({"access": "nobody"})).unwrap(),

      "User"

  );

}

```
