Vetting the cargo

> This being said I sincerely hope Rust doesn't have anything similar to leftpad crate: while I can agree that leftpad may be nontrivial enough to live in some public crate I sincerely hope it would be in a crate with it's friends rightpad, centerpad and other such functions.

Haha, yeah, about that...

I seem to recall someone having made a "leftpad index" for Rust crates, which counted number of lines in relation to how often the crate is downloaded. There are a few very leftpad-y crates. In general, Rust unfortunately follows the npm microdependencies approach, which does not only have security implications (trusting 30 random personal GitHub accounts to not get compromised/be malicious for what could be one regular-sized dependency) but also means nothing ever has a consistent API or release schedule.

An example for a classic leftpad-ish crate that should really be part of the stdlib or a generic terminal library but isn't is "atty", which appears to literally just be isatty() called from Rust, with some Windows and webassembly compatibility code. Its implementation, including unit tests and comments, is 210 lines. However, naturally, it has a sponsor button, 17 releases, and lives in someone's personal GitHub repository. 570 other crates depend on it.

Stuff like this not just being part of the standard library is what has stopped me from using Rust so far.
