Quick Start
You can easily add the {{#switch}}
helper to a rust Handlebars object using
the Handlebars#register_helper
method:
ⓘThis example is not tested
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:
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" ); }
