--files-without-match reports an error when used with a single file path

[ShadowIce]

What version of ripgrep are you using?

ripgrep 0.10.0
-SIMD -AVX (compiled)

How did you install ripgrep?

cargo install ripgrep

What operating system are you using ripgrep on?

Windows 10

Describe your question, feature request, or bug.

I'm trying to get a list of files that contain one word, but not another word. To do that I call "rg -l foo" to get a list of files that I pass on to another call with "rg --files-without-match bar". The call looks something like this: rg -l foo | xargs -i -d '\n' rg --files-without-match bar {}

This doesn't work because --files-without-match cannot be used with a single file. The error message is " output kind PathWithoutMatch requires a file path". However I don't understand why that shouldn't be possible.
Maybe there's a better way to do this? If not I'd really appreciate it if that could be implemented.

Please provide a fully reproducible example, which should include a corpus to search.

If you need an example, use the ripgrep source code with this (it lists all files with an impl block, but no tests):
rg -l -g '*.rs' "impl " | xargs -i -d '\n' grep -L 'cfg(test)' {}

What I would like is to use rg for the second part as well, which probably would be: rg -l -g '*.rs' "impl " | xargs -i -d '\n' rg --files-without-match 'cfg\(test\)' {}

My use case is searching in C++ code for includes that are not needed, e.g. rg -l "#include <vector>" | xargs -i -d '\n' grep -L "vector<" {}

Thanks. As a suggestion, your xargs use is a bit indiosyncratic. rg -l -g '*.rs' "impl " -0 | xargs -0 grep -L 'cfg(test)' is simpler.

Also, xargs is not needed for a reproduction. Here's a very simple example:

$ rg --files-without-match 'cfg(test)' src/main.rs
src/main.rs: output kind PathWithoutMatch requires a file path

$ rg --files-without-match 'cfg(test)' src/main.rs src/main.rs
src/main.rs
src/main.rs

This is definitely a bug. Thanks for reporting it!
