Syntax highlighting highlights 'us' and 'is' suffixes (not 'usize' and 'isize')

[Grazfather]

I noticed while playing around here: http://rustbyexample.com/cast/literals.html

Numeric literals can be type annotated by adding the type as a suffix, with the exception of usize that uses the usize suffix and isize that uses the isize suffix.

Notice the weird wording? Well it had me try out both. 5isize compiles, but 5is has proper syntax highlighting.

I'm pretty sure that used to work but I don't know when that suffix got backed out. Either way, it's not an issue with rustbyexample, it's a problem with [ace](https://github.com/ajaxorg/ace problem). I think it could be fixed by changing us and is to usize and isize here but I haven't tried it so it probably needs verification.

When did is and us get removed? I guess I don't remember it happening.

I'll report it on ace, then.

I am new to rust, so it was all new to me. Looks like it was done this year

He merged a fix into ace so rbe will pick it up once it makes it to ace-builds

👍

Should this also be reworded?

Numeric literals can be type annotated by adding the type as a suffix, with the exception of usize that uses the usize suffix and isize that uses the isize suffix.

(they are no longer exceptions)

yup

Triage: This has been fixed.
