Struct JsonHelper

pub struct JsonHelper;

Get the json representation of the first argument passed. If a second argument is true, the json is beautyfied

 assert_eq!(
   exec_template(json!(42), r#"{{json this}}"#),
   "42"
 );
 assert_eq!(
   exec_template(json!({"a": "42"}), r#"{{json this}}"#),
   "{\"a\":\"42\"}"
 );
 assert_eq!(
   exec_template(json!({"a": "42"}), r#"{{json this true}}"#),
   "{\n  \"a\": \"42\"\n}"
 );
 assert_eq!(
   exec_template(json!(42), r#"{{json (json this)}}"#),
   "\"42\""
 );

Trait Implementations

impl HelperDef for JsonHelper

fn call_inner<'reg: 'rc, 'rc>( &self, h: &Helper<'reg, 'rc>, _: &'reg Handlebars<'reg>, _: &'rc Context, _: &mut RenderContext<'reg, 'rc>, ) -> Result<ScopedJson<'reg, 'rc>, RenderError>

A simplified api to define helper

fn call<'reg, 'rc>( &self, h: &Helper<'reg, 'rc>, r: &'reg Registry<'reg>, ctx: &'rc Context, rc: &mut RenderContext<'reg, 'rc>, out: &mut dyn Output, ) -> Result<(), RenderError>

where 'reg: 'rc,

A complex version of helper interface.
