I had an issue with crate performance in IDE. My Rust crate, ~12000 SLOC, was very slow in VS Code. I figured out some measures against slowdown: split the crate, use less generic-heavy structs.

But I also found out that Serde derive macros were seriously slowing things down. So I wrote my own traits, that were calling Zerocopy's methods to save data.

Now I wanted to test honestly, how slower Serde will be given the same structs.

I made this crate that generates random structures and some stub code to prevent code optimizations. There's a chart with the results on different sizes, and also an example of generated code.

I found that bincode has derive macros now too, and added them. There was packbytes crate, but couldn't write test code for it.

Here's the result table. Please post your comments.
