Use Arch image; Alpine doesn't have Zig 0.7.0 yet
Port everything so `zig build test` works on 0.7.0
The earlier commit got what I was using working on 0.7.0, but I forgot
to run the test suite to ensure everything was updated. Now I have run
it and all of the tests work.
- The varint tests were failing because the `readVarInt` functions are
private. I moved these tests to `src/bare.zig` because I figure these
are internal details that shouldn't be made public.
Add test for duplicate enum values
Better compile error messages
Add note on hash maps to README
Try to support future Zig version[s]
Clean up `void` handling
As it's only supported in tagged unions, might as well special-case it there.
Test tagged union with active void member
Don't zero structs
It causes compile errors with tagged union members.
Update README and main.zig example
Simplify and fix a bug in `readHashMap`
Be more picky about map keys
