The Big Move

Rationale

Some packages and files, especially in accounts/... are not appropriately placed. We should move them to better places in order to make them more visible and better fitting. The changes could either be done seperately or all in once to create only a single breaking change for users.

In the following description, I'll use / to indicate the top level directory and * to indicate all files within a directory.

I found a bls crash that I can not reproduce, it seems that it was just a random fluke, but I'm not 100% sure:
Error:

Hey, I'm currently trying to fuzz a library that was generated from rust and run into an Could not import C (no metadata for C) error.

I found these prs to golang: https://go-review.googlesource.com/c/tools/+/214738/ https://go-review.googlesource.com/c/tools/+/214943/ The second one was merged into master (but not included in the latest release). I also tried to apply the first one, however this gives me multiple undeclared name: C errors.

The library is here: https://github.com/shamatar/eip2537rustwrapper Repro:

  • clone the library,
  • execute the functions in their readme
