[krishnakumar4a4]

Description of the false positive

The argument is being used in the body of the function but flagged unused.

Code samples or links to source code

This is one specific example https://github.com/microsoft/windows-drivers-rs/blob/main/crates/cargo-wdk/src/providers/fs.rs#L29

URL to the alert on GitHub code scanning (optional)

However, false positives for the arguments are generated for all the methods in this module and other sibling modules (exec, metadata and wdk_build).

Hi @krishnakumar4a4,

Thanks for your report. We are aware that the unused variable query has some problems, and we have added a link to this issue from out internal tracking issue. Unfortunately, we cannot provide any estimate on when this may be fixed.
