Rustfmt transformer ignoring configuration

I have a simple Rustfmt transformer on my repository, and the transformer completely ignores the rustfmt.toml file. Running cargo fmt locally in the root folder follows the config perfectly, but the pull request from the transformer (style: format code with Rustfmt and StandardJS by deepsource-autofix[bot] · Pull Request #54 · BigBadE/Raven-Language · GitHub) completely ignores the configuration, as you can tell by how short the lines are compared to the 125 width max.

Is the transformer just looking for the file in the wrong place? Is there any way I can get this transformer to work correctly?
