Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I wrote a package to compute the distance between two geographic latitude, longitude coordinates
I could be mistaken, but https://github.com/golang/geo does it already...
-
Get Coordinates Within Maps Bound Box
s2 a geo library from google can do exactly that, and has an implementation in Go. https://github.com/golang/geo

Protocol buffers database, a Key-Value database on the wire
There's a Java port and bindings for Python. The go port has been a work in progress for a while and the claimed to be at about 40% done. There's a rust port but it is based off of the go port and thus not complete either.

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

GreptimeDB: a new open source database designed for large-scale time-series data storage and processing, written in rust
There are some databases like sled/FlashDB designed to be embedded to other applications even bare metal microcontrollers. But I do doubt the potential bussiness value of a pure embedded database.

Ask HN: Serverless” key value store with transactions?
https://github.com/spacejam/sled
To add transaction support, you probably need a good understanding of how the memtable works in Log Structured Merge trees:
What are some alternatives?
h3 - Hexagonal hierarchical geospatial indexing system
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
S2 geojson - Draw a polygon on the map or paste a geoJSON and explore how the s2.RegionCoverer covers it with S2 cells depending on the min and max levels
rust-rocksdb - rust wrapper for rocksdb
h3-go - Go bindings for H3, a hierarchical hexagonal geospatial indexing system
redis-rs - Redis library for rust
osm - General purpose library for reading, writing and working with OpenStreetMap data
sqlx - 🧰 The Rust SQL Toolkit. An async, pure Rust SQL crate featuring compile-time checked queries without a DSL. Supports PostgreSQL, MySQL, and SQLite.
mbtileserver - Basic Go server for mbtiles
mini-redis - Incomplete Redis client and server implementation using Tokio - for learning purposes only
simplefeatures - Simple Features is a pure Go Implementation of the OpenGIS Simple Feature Access Specification
heed - A fully typed LMDB wrapper with minimum overhead 🐦
