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.

Differential Datalog: a programming language for incremental computation
What is the difference with https://github.com/rust-lang/datafrog? It’s a Datalog engine written by Frank McSherry on top of differential dataflow, that’s used here also

Announcing: MiniRust
C++ is arguably the most complex programming language ever. There is not much to be gained by comparing against the supremum.
Take a look at the languages that rust was influenced by (https://en.wikipedia.org/wiki/Rust_(programming_language)) those aren't languages with straightforward compilation semantics.
There is a reason why rust has a datalog engine build into the compiler (https://github.com/rust-lang/datafrog). Which is imho totally rad and awesome, but really hard to fully form a mental model of without a spec.

Help with iterator efficiency
Datalog may be obscure, but its actually what the next generation of the borrow checker is going to be implemented in, you may find inspiration here: https://github.com/rust-lang/datafrog

Differential Dataflow for Mere Mortals
They used to but Frank McSherry (author of differential dataflow) wrote them a specialized version without all the dataflow infrastructure [1]. It's part of the rust-lang nursery [2] now but hasn't been updated in a while, so I'm not sure what happened to it.

Differential Datalog: a programming language for incremental computation
If you like this kind of thing, google Self-Adjusting Computation.
There's a C++ library that implements it here: https://github.com/cmuparlay/psac
What are some alternatives?
polonius - Defines the Rust borrow checker.
database-stream-processor - Streaming and Incremental Computation Framework
dida - Differential dataflow for mere mortals
differential-datalog - DDlog is a programming language for incremental computation. It is well suited for writing programs that continuously update their output in response to input changes. A DDlog programmer does not write incremental algorithms; instead they specify the desired input-output mapping in a declarative manner.
