Hi @anandkaranubc, I’ve made sure all benchmarks pass locally and I’ve addressed all the lint errors that showed up so far (spacing, import order, header formatting, etc.).
However, I keep running into new lint issues one after another, even after I think I’ve fixed everything. Is there a better workflow or tool I can use to catch all lint errors before pushing or opening a PR?
Also, let me know if I should squash these commits or leave them as is.

@AryanJ18 Thank you for your PR. However, your proposed changes contain significant deviations from our style conventions. I suppose going back through and comparing to other packages to ensure that everything looks and feels like other packages (e.g., in terms of spacing, etc.).

@AryanJ18 The PR looks in good shape overall. Thank you for making the changes as Athan suggested. Just a few changes remain, as mentioned above.

[AryanJ18]

Thank you! I’ll make the remaining changes as suggested and push the update shortly.
