Description

I have a rustfmt.toml that contains many unstable options that I use for some of my personal projects. When contributing to other people's open source projects who use the default rustfmt settings (i.e. dont have a rustfmt file committed), rustfmt will recursively search parents until it finds my personal rustfmt.toml. I would like an option in the rustfmt cli to prevent recursively searching for a rustfmt.toml file.

Research direction

Start by tracing rustfmt's CLI configuration discovery and how it searches parent directories. Define the CLI behavior for ignoring rustfmt.toml, then add coverage for a project with a parent configuration and verify that default behavior remains unchanged.
