Allow for missing modules

[abrisco]

I have a crate that uses some generated source code that fails whenever I run rustfmt before generating it with the following error

~/Code/rustfmthing (main ✗) rustfmt ./src/main.rs
Error writing files: failed to resolve mod `generated`: /Users/abrisco/Code/rustfmthing/src/generated.rs does not exist

The source file looks like this:

mod generated;

pub fn main() {
    generated::greeting();
}

Is there a way to have rustfmt not attempt to resolve modules and instead simply format the file I passed?

Thanks for reaching out. This is a similar request to #5609, and #5611 was opened to provide an option to ignore missing submodules.

You can subscribe to the PR to be notified when the team has a chance to revisit those proposed changes.

You could also use skip_children=true and rustfmt won't try to resolve any submodules. So in your example above only main.rs would be formatted. if you ran

rustfmt ./src/main.rs
