Formatting part of a Rust file with a prettier

[ranile]

I would like to format a Rust file with Rustfmt but have the contents of a macro (html! in this case) be formatted with prettier.

This is required because Rustfmt doesn't touch anything inside a macro invocation - those tokens are ignored. html! has a syntax very similar to that to HTML so Prettier can be used for format it's contents.

Is this possible to achieve? If so, how? If not, would it be possible/feasible to add support for this?
