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.

- Rust project test coverage
-
What are some good rust tools/extentions?
I’ll add tarpaulin, a crate I use for code coverage analysis.
-
Kudos to cargo-llvm-cov - really useful coverage reporting
Any pros/cons compared to tarpaulin?

Code Coverage Tooling
What about tarpaulin : https://github.com/xd009642/tarpaulin
- Measuring the coverage of a Rust program in Github Actions
-
Dare to ask for more #rust2024
Note that the tool cargo-tarpaulin provides code coverage.
-
Is there a rust way for doing TDD?
There is https://github.com/xd009642/tarpaulin for code coverage, but I'm not sure how widely it's used.
-
Uncovered Intermediate Topics
I know giving a link is not a tutorial, but I use https://github.com/xd009642/tarpaulin for this.

What's everyone working on this week (45/2021)?
Writing software test for [Toql](https://crates.io/crates/toql) and shaking out smaller bugs here and there. [Tarpaulin](https://github.com/xd009642/tarpaulin) is such a fantastic tool!
-
GlueSQL v0.7 - INDEX & ORDER BY are newly added.
Code quality also has become quite better than the last year. Almost codes in the project are tested by either unit or integration tests. Code coverage using tarpaulin is above 90%.

Rust: Box Is a Unique Type
>While we are many missing language features away from this being the case, the noalias case is also magic descended upon box itself, with no user code ever having access to it.
I'm not sure why the author thinks there's magic behind Box. Box is not a special case of `noalias`. Run this snippet with miri and you'll see the same issue: https://play.rust-lang.org/?version=stable&mode=debug&editio...
`Box` _does_ have an expectation that its inner pointer is not aliased to another Box (even if used for readonly operations). See: https://github.com/rust-lang/miri/issues/1800#issuecomment-8...)

Bytecode VMs in Surprising Places
Miri [0] is an interpreter for the mid-level intermediate representation (MIR) generated by the Rust compiler. MIR is input for more processing steps of the compiler. However miri also runs MIR directly. This means miri is a VM. Of course it's not a bytecode VM, because MIR is not a bytecode AFAIK. I still think that miri is a interesting example.
And why does miri exist?
It is a lot slower. However it can check for some undefined behavior.

RFC: Rust Has Provenance
Provenance is a dynamic property of pointer values. The actual underlying rules that a program must follow, even when using raw pointers and `unsafe`, are written in terms of provenance. Miri (https://github.com/rust-lang/miri) represents provenance as an actual value stored alongside each pointer's address, so it can check for violations of these rules.
Lifetimes are a static approximation of provenance. They are erased after being validated by the borrow checker, and do not exist in Miri or have any impact on what transformations the optimizer may perform. In other words, the provenance rules allow a superset of what the borrow checker allows.

Running rustc in a browser
There has been discussion of doing this with MIRI, which would be easier than all of rustc.

Piecemeal dropping of struct members causes UB? (Miri)
This issue has been fixed: https://github.com/rust-lang/miri/issues/2964
- Erroneous UB Error with Miri?
-
I've incidentally created one of the fastest bounded MPSC queue
Actually, I've done more advanced tests with MIRI (see https://github.com/rust-lang/miri/issues/2920 for example) which allowed me to fix some issues. I've also made the code compatible with loom, but I didn't found the time yet to write and execute loom tests. That's on the TODO-list, and I need to track it with an issue too.

Interested in "secure programming languages", both theory and practice but mostly practice, where do I start?
He is one of the big brains behind Miri, which is a interpreter that runs on the MIR (compiler representation between human code and asm/machine code) and detects undefined behavior. Super useful tool for language safety, pretty interesting on its own.
-
Formal verification for unsafe code?
I would also run your tests in Miri (https://github.com/rust-lang/miri) to try to cover more bases.
