Struct bracket::helper::if::If

pub struct If;

Evaluates an argument as truthy.

For block execution if the value is truthy the inner template is rendered otherwise each conditional is evaluated and the first one which returns a truthy value is rendered.

When executed in a statement this helper returns whether it's argument is truthy.
