ToyDB rewritten: a distributed SQL database in Rust, for education
Maybe consider sled? https://github.com/spacejam/sled
It's been abandoned for some years, the author was working on a new engine for it and in the last 5 days they started working again on sled proper. However, it's pretty good the way it is (the 0.34.7 release from 2021 https://crates.io/crates/sled), despite the beta warnings

SableDb – a key/value store that uses RocksDB and Redis API (written in Rust)
a few times, seems interesting. The author's also built a lot of other cool concurrency primitives for Rust as well.

Is Something Bugging You?
- Dropbox [3] uses a similar approach but they talk about it a bit more abstractly.
Sans-IO is more documented in Python [4], but str0m [5] and quinn-proto [6] are the best examples in Rust I’m aware of. Note that sans-IO is orthogonal to deterministic test frameworks, but it composes well with them.
With the disclaimer that my opinions are mine and mine alone, and don’t reflect the company I work at —— I do work at a rust shop that has utilized these techniques on some projects.
TigerBeetle is an amazing example and I’ve looked at it before! They are really the best example of this approach outside of FoundationDB I think.

Production grade databases in Rust
There is a valid argument to be made for threads over async in a large percentage of use cases where async is considered the default. If this is what you are referring to however, I don't think they ever referred to async as completely useless: https://github.com/spacejam/sled/issues/1123.

Best local database that works on all platforms including web?
Have you looked into other pure-Rust databases as well, such as sled or GlueSQL which has an SQL interface on top of sled? I wonder how those would compare to Persy.

Are there any embedded databases that have multiple-process support?
I'm not sure what you need. Are these of any use? https://github.com/meilisearch/heed https://github.com/spacejam/sled

Are there a demand for management system of embedded storage like RocksDB? I plan to build one in Rust as the language becoming a core of many popular databases but wonder if there’s a demand. Can’t find any similar project even in other languages.
There is also Sled but as I understand it that is being reworked to use the author's new DB core Marble
