Attribute Macro template_filter 

#[template_filter]

Registers a function as a named MiniJinja template filter.

Syntax

#[template_filter]                       // uses the Rust function name
#[template_filter(name = "filter_name")] // explicit filter name

The function is submitted via inventory and registered into the MiniJinja environment when the TemplateEngine service starts. The inventory::submit! call is guarded by #[cfg(feature = "templates")] in the generated code, so the function definition is always compiled but the registration only takes effect when that feature is enabled on modo.

Requires the templates feature on modo.
