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.

When to flush()?
This is an example from the Termion crate:

How difficult is ncurses?
There are plenty of terminal UI libraries that are actually nice to work with. For Python, there's Textual and PyTermGUI. For Rust, there's ratatui and Cursive (or, if you want something a bit lower level, crosster or termion). For Go, there's bubbletea.

Writing to a real stdout in the following adapter pattern
But let's say I want to write to Termion's raw terminal: stdout().into_raw_mode().unwrap();

How to write the mock version of this trait method?
And I implemented it for a TermWriter struct (Note: DetectCursorPos comes from the Termion crate):
-
How to test the cursor's position in the following test?
The following code stores the user input and cursor position in a raw terminal (using Termion):
-
Testing the stdout of a RawTerminal
That being said, termion has already handle this for us (an example).

Termion: recreating Backspace for deleting characters
I'm trying to recreate the Backspace functionality with Termion in raw mode. Right now, it works as expected if I'm deleting the last character. But If I move to the left with the Left arrow, then delete a character, the characters on the right of the cursor won't move to the left.

When rustc developers run out of error messages to write
Termion crate (https://crates.io/crates/termion), and very careful observation of a rust error. Hope your friend finds it useful ;)

Crate for an interactive terminal program.

Hey Rustaceans! Got an easy question? Ask here (35/2021)!
If you just need basic printing and limited input then I'd choose either crossterm or termion. If you want a full tui, then tui-rs is really good.

Getaddrinfo() on glibc calls getenv(), oh boy
The problem is that this effects higher languages too, because they often build on libc. And on some OSes, they don't have a choice, because the system call interface is unstable and/or undocumented).
For example in rust, multiple time libraries were found to be unsound if `std::env::set_env` was ever called from a multi-threaded program. See:
https://github.com/time-rs/time/issues/293 and https://github.com/chronotope/chrono/issues/499

ZeroVer: 0-Based Versioning
> I think library authors should be more relentless and break compatibility every few years. We just need some conventions to not do so very often.
I indeed did this years ago---I'm the original author of Chrono [1]---and it wasn't well received [2] [3] [4]. To be fair, I knew it was a clear violation of semantic versioning but I didn't see any point of obeying that until we've reached 1.0 so I went ahead. People complained a lot and I had to yank the problematic release. By then I realized many enough people religiously expect semantic versioning (for good reasons though) and it's wiser to avoid useless conflict.

Simple, fast and safety alternative for unzip
On that note, it would also be good to configure cargo-deny so that a CI pipeline and any maintainer can easily audit the current dependency versions. Sometimes CVEs require a new major semver (looking at you, time 0.1.x and thus chrono 0.4.x), so it's not enough to rely on people installing the tool with semver-compatible updates. Automatically auditing dependencies is really important, and given how easy cargo-deny makes it, I don't think many projects have any excuse not to configure it.

Is it unidiomatic/anti-pattern to use the return keyword ?
The example has been randomly taken from the [Chrono][https://github.com/chronotope/chrono/blob/main/src/offset/utc.rs] crate.

Will Rust drop dependency on libc and make direct system calls? when ? (Please don't mention no_std case)
libc isn't "just a wrapper". Is a massive legacy codebase filled with hacks, UBs and bugs: https://github.com/chronotope/chrono/issues/499
- chrono 0.4.20 has been released, fixing the RUSTSEC-2020-0159 issue
-
chrono 0.4.20-rc.1 has just been released!!
Would love to have people test this, you can leave feedback here: https://github.com/chronotope/chrono/issues/674.
