Announcing zune-jpeg: Rust's fastest JPEG decoder
Congrats, but you dropped this.

Do you ever use unsafe { .. } when not implementing custom data structures or interacting with external C code?
Alternatively, you can round up the array length to the nearest power of 2 and use cheap bitmasking instead of branching bounds checks. If it goes wrong, it will access the wrong element but will not result in any code execution vulnerabilities. Here's an example of this in zune-jpeg.

Good example of high performance Rust project without unsafe code?
gif, png, zune-jpeg are on par with their C counterparts in terms of performance

Where do people learn to write truly quick software?
Based on some experience writing a jpeg decoder library, I'd like to give my two cents worth of information

What are you using Rust for?
Answer pretty fast

png crate gets an ultrafast compression mode, up to 4x faster decompression
Encoding images to PNG with the "fast" compression mode is now an order of magnitude faster. This is achieved using a custom Zlib compression implementation that leverages assumptions about the patterns in PNG data to get reasonable compression ratios at phenomenal speeds.

Introducing zune-png: extremely fast PNG decoding in Rust
However, the latest release of the png crate - published less than a day ago - has an ultrafast compression mode that's slightly faster than the QOI reference implementation at a comparable compression ratio. So basically you get the properties of QOI in a much more widely used image format.

Announcing zune-jpeg: Rust's fastest JPEG decoder
In other areas, miniz_oxide is faster than miniz, Symphonia is faster than ffmpeg on most codecs, the not-yet-announced zune-png beats both libpng and the more heavily optimized libspng, and the png crate is getting considerable improvements too and also beats libpng.

When soundness isn't worth it
Fun fact: libpng-sys was so difficult to create safe Rust wrapper for that people just wrote their own, 100% safe Rust PNG decoder: https://github.com/image-rs/image-png

Anyone want to speed up a PNG decoder?
I didn't get time to finish the full spec for my attempt at a PNG decoder but it was working on common cases and was faster than image-png at the time https://users.rust-lang.org/t/new-rust-png-decoding-library/30952. I suspect it's not the case anymore since it changes it's deflate crate usage. Here is the perf issue on the image crate https://github.com/image-rs/image-png/issues/114. My code was way simpler than the one in the image crate so that might still be worth a read if you are interested.

Wuffs PNG decoder faster than rust
The crate actually forbids unsafe. There's nothing necessarily wrong with unsafe code, but not having it provides a nice assurance. Plus if you are willing to tolerate (well audited) unsafe code then you may well be better off just using libpng.
