made all rust operators tokenize as unit

[flying-sheep]

this allows fonts like Fira Code and Monoid to render all rust operators with a ligature.

“=>” is an operator used in matching, so it makes sense to include it

[flying-sheep]

i had to get around precedence messing things up by adding a second “Comparison operator” group containing <=, >=, <, and >. should i explain that in the comment?

[zargony]

That's great, thanks a lot (I just started to use Fira Code ;)).

A short comment explaining the second comparison group would be nice. Also, one or two cases in test.rs that demonstrate the proper highlighting would be nice as well (unfortunately we don't have automated tests for proper tokenization yet)

@flying-sheep, I noticed you've (accidentally?) thrown away the bitwise or logical complement operator (!) in your changes.

[flying-sheep]

both fixed

[chriskrycho]

Just following up on this: it looks like -> is working properly, but => is not—so function returns look great; match expressions are still old-school.

[flying-sheep]

so you mean with or without my changes?

[chriskrycho]

@flying-sheep Ah, I see. I incorrectly assumed that a month-old change would be in a release! I'll try the patched version of the package in a bit.

@zargony can you push a release of the package sometime soon? (I understand if you're busy, of course, so "soon" is a relative term, not a demand for immediacy. 😉)

[flying-sheep]

yeah, this PR is still open, i.e. the changes aren’t merged. if they were it would be purple, not green 😄

[chriskrycho]

Heh, right. It's been a _looong_ week, the kind that involved driving from NYC to Raleigh **after** an eight-hour workday on Monday and went from there.

[flying-sheep]

no need to justify 😆

[flying-sheep]

@zargony do you want to pull this or do i have to do anything?

[zargony]

Sorry that it took this long. Great work! Thanks a lot, @flying-sheep

[flying-sheep]

great, thanks!

[chriskrycho]

Awesome!
