@gavofyork +1
guess lack of test is an issue, not a grumble
it will prevents further comfortable modification of the code

It would be more optimal to append rlps directly, without converting to transaction/header structure. transactions_rlp and uncles_rlp can be added to BlockView

we skip a couple of the fields from the header, i think we have to at least decode that.

block chunking is significantly faster than state chunking even so

can the error be returned instead of panic happening with the assert?

this assert should be removed outright actually. i added it while debugging but it will only fail if snappy has a bug

I added account and block tests.

I will add tests for the overall snapshotting mechanism once I implement snapshot restoration. Right now there isn't anything I can see to meaningfully test in that module.
