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.

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

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.

Options for SVG / Text rendering on 2D pixel buffer
I've seen resvg as a potential pick, but it feels huge and seems to be importing skia, which itself is a whole rendering engine. Furthermore, I have no idea if I can pass my own 2D buffer to resvg and let it draw to it.

png crate gets an ultrafast compression mode, up to 4x faster decompression
For example, when converting vector SVG images to raster PNG images with resvg, most of the time is spent compressing the PNG image. This is a lot of wasted work if we just want to read the image instead of transferring it over the network! The fast compression mode eliminates all this wasted work, resulting in huge performance and efficiency gains.

Is coding in Rust as bad as in C++? A practical comparison
Just as a point of reference, I have a ~75KLOC project (includes dependencies) called resvg which takes just 4s in the debug mode and 8s in the release mode to build on M1 Pro.

Good example of high performance Rust project without unsafe code?
resvg is very fast, although the performance depends on the exact SVG you feed it - sometimes faster than librsvg, sometimes slower (although librsvg is also written in Rust now, it does use unsafe while resvg doesn't)

How to run this Rust project?
So I am absolutely clueless about Rust and just installed it an hour ago to use this tool called "usvg" https://github.com/RazrFalcon/resvg/tree/master/usvg

I think more Rust devs should focus more on rewriting software that is prone to exploitation
So, all you gotta do is rewrite the parsers. Funny you mention librsvg because there is a library called resvg that has a thumbnailer implementation for Windows Explorer. https://github.com/RazrFalcon/resvg
