Struct GlobalParameterHelper

pub struct GlobalParameterHelper { /* private fields */ }

Gets a value from the global parameters (those key=value’s would be provided as parameters of codegenr execution)

let mut params = HashMap::<_,_>::new();
params.insert("k".to_string(), json!("v"));

assert_eq!(
  exec_template_with_global_params(json!({}), r#"{{global_parameter "k"}}"#, params.clone()),
  "v"
);
assert_eq!(
  exec_template_with_global_params(json!({}), r#"{{global_parameter "non_existing"}}"#, params),
  ""
);

An error will be raise if a non existing key is asked and second parameter is true

exec_template_with_global_params(json!({}), r#"{{global_parameter "k" true}}"#, Default::default());

Trait Implementations

impl HelperDef for GlobalParameterHelper

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.
