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.

Hoogle for Rust?
Instead of searching functions based on their type structure (like Hoogle), you could search for functions that "consume"/"produce" values of given types (like OCaml's Merlin). I think Rust already computes variance of type constructors, so such a tool just would have to obtain this information.

Dot completion
Assuming you followed the instructions you got when you installed merlin (shows up as part of opam's output), you either need a manually created .merlin file to tell it where to find things, or a dune file that lists dependencies with which merlin can auto-create its own. Preferably the latter: use dune and let merlin do the rest.
However, after posting this question I stumbled upon this Github issue where they say it isn't supposed to work out of the box and you're supposed to bind a key to it by editing your .emacs file. Turns out the default .emacs file binds auto-complete to "backtab" which means Shift+Tab but that didn't work. I did eventually discover that I can get some kind of completion by binding backtab to completion-at-point like this:

Advice/best practice/arhitecture pattern for building language with LSP in mind?
Self-advertising: I partcipated to the writing of Merlin: A Language Server for OCaml (Experience Report), which explains the overall design of Merlin, a language server for OCaml. A key idea of Merlin are that classic lexing-parsing-typing pipelines can easily be adapted to be incremental for a Language Server, especially when they are using immutable data structures.

Language Server built into the compiler ?
Self-advertisment: we wrote a paper on how the Merlin tool does this for the OCaml programming language, obtaining good incrementality thanks to well-chosen (and not so large) changes to the existing batch-compiler implementation.
