@vitiral are there any plans to continue with this project? I would be interested in implementing some more types, namely i8, u8 and i16, probably some more too

[vitiral]

my original use case for this was to handle variables in artifact. However that proved to add too much complexity so variables are all but dropped.

However, I still think this is a generally useful library and am happy to accept PRs.

Let me see if I can get a travis instance up and running, which will make things a lot easier for me.

Sure no problem 👍

@seemyvest Is this code almost identical to the i64 method? If so, I think I would like to:

• convert i64 into a genric macro that can generate these
• just generate all the implementations using the macro

If you do that work, testing them all should be pretty easy, as the tests will be identical for most of them.

The travis changes have been pushed. Please rebase and repush.

Let me know if you like the design choice of using generating macros and unifying the tests.

[ghost]

Yeah that's better than writing essentially the same code, I'm happy to do that, I'll just need to look into rust macros a bit more
