master isn't compiling

[ckaran]

I just pulled the latest master (d5df478), and got the compilation errors below. Any ideas?

[RustyYato]

Looks like I broke something upstream in typsy, I'll get that fixed tommorow.

[RustyYato]

Update: it looks like something broke because of nightly changes. I previously had an older nightly, and that compiled fine. Updating rust broke it. sigh I supposed I signed up for this with nightly :(.

[RustyYato]

This is a bug with the current nightly, see rust-lang/rust#81211. I'll keep this issue open until that is resolved. I would revert back to an older nightly for now.

[ckaran]

😞

Eh, it is what it is. The point of nightly is to catch these kinds of bugs. Unfortunately, I stole all the time I could steal from my PhD. for at least a couple of days. Maybe once I have some more plots and stuff written up, I'll be able to come back and do more work on this project. I just need to be able to have 3-4 clones of me running around, so that I can get more work done!

[RustyYato]

Actually, I just noticed we don't use typsy::anon (the only affected module), which is also guarded by the macros feature. I think we could just say default-features = false for the typsy dep and be on our way.

[ckaran]

Nice! I just merged master into examples_singly_linked_list, and it all compiles. As I have some down moments, I'll work on it. Assume that examples_singly_linked_list is half-broken at all times though, at least until I do a pull request.
