can we merge this ? Would be required for #111659

[michaelrj-google]

LGTM, do you need me to merge this for you?

[github-actions]

✅ With the latest revision this PR passed the C/C++ code formatter.

[Sh0g0-1758]

@michaelrj-google there were two more files for which I changed the type I to InType and OutType. If that also looks good, then please merge.
