Nice that #[cfg(feature = "encryption")] macros are now enabling full functions. page_ordinal -> page_index is great for consistency too. I'm cringing a little bit that index and skipping was broken, sorry about that.
No comments for changes.

Looks good, thanks @adamreeve!

Would you like to review this too @alamb or are you happy for me to merge? |
Unless you have something specific you would like me to review, I am very happy to have you merge it -- I think @etseidl 's review is more than adequate. Thank you for checking. BTW in this repo we just hit the green button on the github UI (no extra merge scripts, etc) |
OK great, thanks. I didn't have anything specific in mind but just wasn't sure about the process and how widely my Arrow committer privileges should be used :) |

Which issue does this PR close?
Closes #7629.
I also noticed that skipping pages in encrypted files was broken so have fixed that too.
What changes are included in this PR?
SerializedPageReaderto reduce the use of#[cfg(...)]inline. To work with the borrow checker, I created a newSerializedPageReaderContexttype to hold theCryptoContext.SerializedPageReader::get_next_pageso that page headers and page data are decrypted when page indexes are used.SerializedPageReader::skip_next_pageto update the page index so that encryption AADs are calculated correctly.Are there any user-facing changes?
Only bug fixes.
