Trait Implementations

impl HelperDef for TrimHelper

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.
