Serializing mdast to markdown

[Enoumy]

(Whoops accidentally hit enter before drafting a content for this question, my apologies for the noise!)

Hi! I have a perhaps newbie question! I can use markdown::to_mdast to go from &str -> Node. Is it possible/is there a function to go back to a string - Node -> &str` - in a way that roundtrips?

I came across Node::to_string, and it does seem to convert nodes into a string but it also deletes the links/titles/and most other ast nodes, which if re-parsed again, results in a different ast. Unsure if this question is reasonable/within the context of this crate, but is there an alternate function elsewhere that is round-trippable to/from &str <-> Node? I am also happy to take a stab at implementing this "rountrippable" unparser function myself, but was wondering if a function like it already existed.

For further clarification, by "roundtripping", I would be writing a property based test, like markdown::to_mdast(to_string(node)) == node be true for all node's.

Thanks!
