Can't compile Catalytic 0.1.20 version with scylla_macros 0.2.2

[guvenir18]

Hello, thank you for this great crate.

My issue is suddenly, I can't compile this crate, I get this error:

failed to resolve: could not find LegacySerializedValues in _macro_internal
--> ../.cargo/registry/src/index.crates.io-6f17d22bba15001f/catalytic-0.1.20/src/table_metadata.rs:34:17

34 | #[derive(Debug, scylla::ValueList, scylla::FromRow)]
| ^^^^^^^^^^^^^^^^^
| |
| could not find LegacySerializedValues in _macro_internal
| help: a struct with a similar name exists: SerializedValues
|
= note: this error originates in the derive macro scylla::ValueList (in Nightly builds, run with -Z macro-backtrace for more info)

Problem might be related to scylla_macros crate. I could compile until yesterday. I compared Cargo.lock files and only difference was scylla_macros crate version is now 0.2.2, which was 0.2.1 until yesterday. 0.2.2 version came yesterday.

Hey @guvenir18, thanks for your compliment.

The scylla rust driver has been updated this week to a new version with breaking changes. I want to update this crate asap but I am blocked by scylladb/scylla-rust-driver#890.

@Jasperav Thank you for your quick response, we will wait for them then.

I also want to ask another question which is not related to this issue. I want to modify Transformer so it maps TIMESTAMP values into i64 type, not scylla::frame::value::Timestamp. Is this possible ?

[Jasperav]

I see that there is no way of converting types sadly... what about changing the timestamp type to a bigint? Thats how I did it, works fine if you only store milliseconds and not date related stuff like timezones

[guvenir18]

Thank you for quick answer, that is probably best solution. I know I asked a lot but one last question.

I am trying to write a query using "query!" macro which is "select token(user_id) from users where user_id = ?". This query normally works, I am working on implementing your crate on existing project. I get an error, saying "illegal column: token(user_id)" error. Does this macro works with token function or am I doing something wrong?

[Jasperav]

Oh you can ask anything :) Hmm no the token method does not work yet. I read about it here and the return_type can be dynamic? https://opensource.docs.scylladb.com/stable/cql/functions.html Maybe I can make something easy so that it always returns a i64, does that sound good?

[guvenir18]

I am new to Rust and database stuff so I am still learning, thanks for your help :) i64 type would be enough for my case.

@guvenir18 The issue you described here is our (ScyllaDB rust driver team) fault, we accidentally released a semver-incompatible change in 0.2.2. Catalytic 0.1.20 should we usable with the driver in version 0.10 but we broke that - sorry, we will fix that soon.

For the time being, you should downgrade the scylla-macros dependency in your lockfile - the following command should work:

cargo update -p scylla-macros --precise 0.2.1

This should now be fixed - scylla-macros 0.2.2 was yanked, and re-released as 0.3.0
0.2.1, used by scylla 0.10, was released again as 0.2.3.
So now a cargo update should fix this problem.
