please upgrade to quickcheck 1

[dkg]

the quickcheck crate is at version 1.0.3 now. it would be great if the capnp crate migrated from its dependency on quickcheck 0.9 to quickcheck 1, as that looks to be a more stable API.

[dkg]

The main issue is that quickcheck 1 has Gen as a struct, whereas 0.9 has it as a trait, and capnp uses it as a trait. See for example https://github.com/BurntSushi/quickcheck/issues/277. Sorry to not have better advice on how to make this transition.

I expect that upgrading quickcheck should be straightforward. When we do that we should probably bump the version number of the capnp crates (from 0.14 to 0.15). I hesitate to do that immediately -- it'd be nice if we could batch some of other non-backward compatible changes too, to minimize version churn. One that I have in mind is cleaning up the traits with Generic Associated Types, but unfortunately support for those seems to have stalled somewhat https://github.com/rust-lang/rust/pull/96709.

I'm working on a fix that i think won't actually change the capnp API at all (with some explanatory help from good folks over at sequoia). I'll submit that shortly. if you think that it does warrant a semver-incompatible bump, i'd be interested in understanding why, i'm still trying to get my head around these details.
