How do I manually configure my rust formatter?

[Dangerise]

I need to configure my rust formatter manually for some reasons, I try to simply use rustfmt, but rustfmt will write nothing to stdout when the input is not correct, and it make my source file empty.

So, how do I avoid that

formatter = { command = "bash", args = ["-c", "rustfmt | dx fmt -f -"] }

It needs to have a non-zero return to indicate that formatting failed IIRC

I learnt, so is there a way to do this without editing the source code?
