Thanks. I don't need to use anything in the structs (at least now), just as the thing to pass around to the other c functions. Do you know what I should use instead?

What you used looks fine to me, thanks! Where do you use atoi? It got removed because Crystals own to_is got improved.

I have a C string from the driver, and I didn't want to copy it out of the result and into a crystal string just to turn it into an int: https://github.com/will/crystal-pg/blob/master/src/pg/decoder.cr#L60

Ah, I see!
