cpp-vs-rust VS resvg

> They seem to have chosen to use mold for C++ and not for Rust after seeing that it gave little benefit for small projects, but I would expect that to change as the project scales.

The benchmarks show Mold for both Rust and C++. This wasn't explicitly stated in the article; sorry. https://github.com/quick-lint/cpp-vs-rust/blob/f8d31341f5cac...

Very well-researched article (in my uninformed opinion because I've done virtually no benchmarking). I'd summarize it as, Rust doesn't significantly improve build times over C++ for a project where you need to frequently recompile to test the logic of the code. I gather that the Rust code is pretty idiosyncratic (using raw pointers rather than slices and custom owned and borrowed string containers with i32 length and capacity fields), but I don't know why more idiomatic Rust code would be faster to compile, and it could be very different, so a worse comparison. The results aren't relevant for me because I use Rust mainly for the language features and don't have a project with terrible compile times or the need to often rerun tests, but there might be other C++ projects in the same boat as quick-lint-js that would consider moving to Rust if it compiled faster than C++. Hopefully the efforts of people like u/nnethercote will make that happen.

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.

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.

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.

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)

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

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
