Struct tui_markup::generator::helper::NoopCustomTagParser

pub struct NoopCustomTagParser<S>(_);

A fake custom tag parser which always fail.

Why need this

If a tag convertor support custom tag and you also want it to be optional and impl Default trait, normally you will use a Option<T: CustomTagParser<Custom>> in the convertor.

But the user still need to provide some type of that T(which the usually can’t) even if they do not want custom tag.

With this type, you can add a T = NoopCustomTagParser<Custom> in struct to make them happy.
