Goal

Today I will tidy up various small things.

Plan

• Add clippy lints to prevent many causes of panic.

• Change chunk labels to be URL friendly in the same way identifiers are.

Notes

• Enabled clippy lints:

  • clippy::panic
  • clippy::panicking_unwrap
  • clippy::unwrap_in_result
  • clippy::unwrap_used

• This required fixing many places, but all straightforward. Most annoying part of this is that the lints are meant to apply to production code, but they also apply to test code. No matter.

• Merged these changes.

• For URL-safe labels, I'll change things so that labels are always UTF-8 strings, but also so that they may only contain URL-safe characters. Actually, a subset will do: upper and lower case letters (a through z), digits, dot, and dash. This means they do not need to be encoded in URLs, which makes things simpler.

• I kept the label creation code very simple, but still, on my laptop:

  09:03:47 > cargo run -q --example encode-labels --release -- 1000000
  encode label 1000000 times
  duration 0.727571128 seconds
  labels/s: 1374436.0675070658
  

• That's over a million labels per second. Good enough for now.

• Changed all the code to use new label type and dropped the old one.

• Merged this change, too.

Summary

Made some simple tidying up. That was all I was able to do today, having slept badly.
