heaths@fosstodon.org@jarkko even though it looks like a straight port, what I’d like to see is an expert panel-reviewed library. Some functions need to be constant time, for example. The https://github.com/RustCrypto org claims to have at least a couple reviewed, but this is critical.
Frankly, I’m surprised that, unlike many other frameworks’ standard libraries, #rustlang - advertised as a secure language - has no crypto.

Python is pretty nice for emulating a C program as you can make it call same things as with C. So I actually have like crypto libraries for trying out stuff because they have smooth API and then use something else for the end product.

Rust is a modern language, and e.g. I like the idea of procedural macros. But why create standard library, which takes greatest hits of 80s POSIX tape-drive alike File API and container types from 90s Java that I don't get.
It was pretty apparent in 2016 that you mostly just map memory, and storage is non-volatile RAM. There's lot of these types of contradictions in Rust, and variance in stock API quality.
Personally I use this as my basic memory API https://github.com/rust-vmm/vm-memory, and more like to to this direction should have been I/O API design of stdlib in 2016 (despite being part of rust-vmm, it can do all types of mmaps).
Not even joking when I say that this my favorite part of Rust's stdlib: https://doc.rust-lang.org/std/marker/struct.PhantomData.html. This one I do like.
The comment about crypto library is IMHO even more to the point given that not only Rust was designed with the borrow checker but it was also made by Mozilla for use in Web Browser development. The first presentation I saw about Rust was at LinuxCon EU 2014, and it was more about Servo than Rust itself.

@pinkforest Like for instance. What would you possibly do with a re-allocating vector in any modern systems software? For small chunks, create large enough fixed arrays. For data that needs to scale dynamically however many gigabytes of addresses can be mapped with a total zero cost, and the #PF handler takes care of the rest. Finally there is an option to manually scale the space down with fallocate() (FALLOC_FL_PUNCH_HOLE).
This is standard stuff in modern C systems software. If this is over the top, then I tend to think that probably Java or Go would be better picks in the first place.I just use Python then because more than liking a tool, I like measurable value, which cannot be just my liking. Self-deception IMHO :-)
