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.

Hello World in Go From Rust
Golang uses cgo to communicate with external C libraries and Rust uses FFI (Foreign function interfaces) to export C functions. Additionally, a library for automatically generating bindings can be used to generate the header files (.h). In our case, we'll only be exporting two C functions, so using cbindgen is overkill but we'll use it regardless because why not? Firstly, we'll write the rust functions we want to export. We'll start by creating a new rust library:

As a 2-step approach, you could also probably use https://github.com/mozilla/cbindgen and then Nim's native C FFI.

ffizz: Build a Beautiful C API in Rust
The tooling for the first kind -- calling Rust from another language -- is a bit less developed, and tends to rely on code generation that doesn't necessarily produce a natural C API. cbindgen, uniffi, cxx, and Diplomat all take this course.

How can I use rust libraries in zig/C
There's also cbindgen for automating the generation of C headers once you've got your code in the right shape and you'll also want to read the Rustonomicon.

Rust FFI and cbindgen: Integrating Embedded Rust Code in C
Later we'll see what cbindgen essentially does is receive a configuration and a Rust library and then spit out a C header (.h) file. One might think that what cbindgen is doing might not be that special and can be done by hand. In which some cases that might be true if the project is simple enough. Though additionally as the cbindgen documentation states:

Nautilus just fucked me. (Gnome paper cuts)
Fuck it, I'll take the bait. Rust allows for amazing C interop by allowing for exporting of C types as a dynamic library, like C. Unlike C, this still allows for Rust's advanced checking at compile time. librsvg is one such library that is being used in the GTK ecosystem that is also almost completely Rust. You can use tools like cbindgen to generate C bindings.

Or alternatively cbindgen to create the header file from the Rust source.

Nim v2.0 Released
That looks interesting. Unfortunately it looks like it hasn't been updated in a while? Is that because it's complete or a lack of interest?
For example, the approach mentioned at the bottom of the README of integrating via nlvm (https://github.com/arnetheduck/nlvm) sounded great but appears to be unpursued.

Nim Version 1.6 Released
Being able to compile to C, C++, ObjC, and JavaScript natively (and LLVM using https://github.com/arnetheduck/nlvm ), along with an excellent FFI (including to and from Python) means you don't need to rewrite dependencies as you can use them directly. Nim is great at glue code - arguably better than Python.
Along with general language characteristics such as being high level and productive like Python, but with intricate "bare metal" control when you want it, really does make it suitable for writing almost everything.
