New swatch code fails to compile on 32-bit machine

[peter9477]

Summary

This code works only if usize is 64 bit:

helix/helix-view/src/theme.rs

Line 310 in 7ebf650

Highlight(usize::from_ne_bytes([

On 32-bit you get this error:

Given that this code is still covered by a PR (and the issue is noted there), I guess making this issue was a mistake? If that's true feel free to close. I didn't think to check PRs before adding it (because I'm a noob here).

Its fine, when that gets merged it will just close this issue👍

I feel like we should have a test for a 32-bit machine? CI should've failed for this ideally

Github doesnt offer 32bit CI runners as a standard offering: https://docs.github.com/en/actions/using-github-hosted-runners/using-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories
