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.

How can I do a context switch with rust?
I'm trying to first target the ARM Cortex-M so I've been looking at crates like cortexm-threads but I can't seem to get them to run without a hard fault. Is this maybe the compiler over optimizing?

I Want to start leaning OS development on microcontrollers, any advice?
u/Red3nzo, I have done something similar to what you want to do. Check these links if you are interested: Harsark.rs: A safe and lightweight real-time Kernel written in Rust Cortexm-threads: Simple context switching library for ARM Cortex-M MCUs in Rust

Do World Need Another RTOS?
You can check out the YouTube videos [about building your own minimal RTOS](https://www.youtube.com/playlist?list=PLPW8O6W-1chyrd_Msnn4LD6LBs2slJITs). This minimal RTOS (called MiROS) is used as a teaching aid. The project is also available on GitHub.

How can I do a context switch with rust?
I've checked out C implementations like os h and (MirOS)[https://github.com/QuantumLeaps/MiROS] but when I port them to rust (even with C2Rust) they cause hard faults too.

A Tiny RTOS Simply Explained
To see "A Tiny RTOS Simply Explained" you might want to watch the RTOS video playlist on YouTube. The videos teach about the RTOS by building a "Minimal Real-Time Operating System" (MiROS) for ARM Cortex-M, which is available on GitHub.
-
path of learning the arm cortex-m embedded c programming?
For example, in the segment about the RTOS, you witness building a "Minimal Real-time Operating System "MiROS". The MiROS code is available on GitHub, and you can keep adding to it other features. Building a functional RTOS is a great way to learn about RTOSes.

How to find out how to write an operating system
You will build there a small "Minimal Real-time Operating System (MiROS)" for ARM Cortex-M. You will start with performing context switching manually, and then you will automate the process in assembly. Then you will build schedulers, first time-slicing round-robin and then preemptive, priority-based. You will learn about real-time and Rate Monotonic Scheduling. You will see how all this works using a logic analyzer. The RTOS code, and the examples are available on GitHub.
