After putting 60 entries into the database... every 20 entries have a different key schema, e.g.
1st 20: "messages/year/month/index"
2nd 20: "locations/year/month/index"
3rd 20: "something/someone/anyone/index"

When I use the iterator to seek out "messages"... I print out the messages keyed entries correctly and goes on to print the other entries which aren't related to messages... the whole time iterator.valid? happens to be true. After printing the said entries, it adds the following:

Invalid memory access (signal 11) at address 0x18
[0x430906] ???
[0x426280] __crystal_sigfault_handler +32
[0x7f13536a1390] ???

[0x7f1352c84830] __libc_start_main +240
[0x40b259] _start +41
[0x0] ???

This is the iterator part of my code

while iterator.valid?
  iterator.next
  puts "#{iterator.key} - #{iterator.value}"
end

iterator.destroy

The readme suggests using 0.2.0 in the shard.yml, but that version can't be resolved currently.

An old issue was opened as far back as January this year, not even a comment on the issue by the maintainers.

Can't resolve 0.2.0 when installing with the README.md's instruction... if you happen to remove the version part you get this error for version 0.1.0
