May lost data when power off or crash?

[lancexin]

I just looked at the code and didn't run it. I'm just worried about whether data loss may occur in certain situations. I hope the author can provide an answer:

I saw that the write method in RingCryptoWrite is to first write to the buf. If the buf meets the block size requirement, the data in the buf will be encrypted and written to the disk. But if buf is not fully charged, this data is only temporarily stored in memory and not written to disk. If there is a power outage or program crash at this time, will this data be permanently lost?

good catch, it can happen actually also when writing the filled buffer
but we have #48 to take care of this, which is in progress

thanks for reporting this, it's really of a good eye paying attention to details :)

@lancexin how would you like contributing to #48 and fix this too?

I'm sorry, but I'm still new to Rust—I haven't even written a complete Rust program yet. Right now, I don’t have the ability to write stable, production-ready code like you.
WAL is a great idea, but it’s currently too complex for me. I’ll focus on mastering the basics of Rust first.
Also, thank you for your reply.

got it, maybe it would help you join our community https://xorio.rs/ . We will also organize a Rust for beginners course in few months maybe, will announce it on our Discord. We stated one but mostly because of time issues we postponed it and we plan to create another one with lessons learned. This are the videos from last one https://www.youtube.com/watch?v=VX1SRZ65oi4&list=PLzPrvFZbOBZAuI9hACGxZLq82M1yjG7Z9
In any case, if you need any help with Rust, feel free to let me know, and also check out projects on he community site from above and other activities we do, maybe you want to join some.

Glad to have met you and wish you a great journey in IT world :)
