How to disable formatting for comments?

[hirrolot]

I have an MD table like this:

| Feature | Description |
|----------|----------|
| blah | some long long long long long long long long line |

I also have wrap_comments = true in my rustfmt.toml. As a result, rustfmt breaks the long line and disfigures the table. The comment itself is located at the top level of a .rs file and must be treated as a public documentation.

Can I tell rustfmt to skip this table?

As a workaround:

#![cfg_attr(feature = "nightly", feature(extended_key_value_attributes))]

// ...

#![cfg_attr(feature = "nightly", doc = include_str!("features.txt"))]

Where features.txt is a file that contains the vicious comment.

[jyn514]

#![cfg_attr(feature = "nightly", doc = include_str!("features.txt"))]

FYI this doesn't work like you expect it to: rust-lang/rust#82768

Thanks for reaching out but going to close as a duplicate of #4210. Please let me know if you feel like this is different/not a duplicate.

The fix has already been made but just hasn't been released. I will try to pull this into the next release, though no guarantees.
