Compilation error on 32-bit architecture

[frol]

Describe the bug

error[E0308]: mismatched types
  --> /home/dots/.cargo/registry/src/github.com-1285ae84e5963aae/near-primitives-0.14.0/src/rand.rs:62:50

   |                             arguments to this function are incorrect

To Reproduce

Compile near-primitives for i686 (32-bit) target (wasm probably will have the same issue).

Expected behavior

It should compile just fine.

Version (please complete the following information):

• nearcore commit/branch: 0.14 release and master branch

Sort-of dupe of https://github.com/near/nearcore/issues/7137.

At the moment, no effort is spent on making nearcore crates (with the exception of near-account-id) usable outside of nearcore.

In the ideal world, all re-usable functionality would be available from near_sdk, but, as far as I know it, no one is actually working on that.

Practical advice would be:

• ~~copy-paste~~ vendor the relevant struct definitions or what-not. While the crate itself is unstable, the binary ABI exposed by nearcore is stable
• create some sort of discussion/tracking issue with dev-platform roped in which tracks how we solve the underlying problem here -- as far as I know, there isn't organized effort here yet

It was not near-sdk, but near-jsonrpc-client-rs, which depends on near-primitives, and I tried to compile near-cli-rs for x32 platform and failed. Given that it was just one thing that borked, it hoped to find some time to fix it.

I needed to compile near-jsonrpc-client (and subsequently near-primitives) for x86 again and remembered that I did not mention the hotfix here. In order to get through the compilation error, I patched the file in question in my local cargo registry cache folder by replacing the body of this sample function with 0 (this function is not used by near-jsonrpc-client).
