Using library with ZIO service pattern

[PawelJ-PL]

Version: (e.g. 4.6.0.1) **Module**: (e.g.quill-jdbc) **Database**: (e.g.postgres`)

I'm trying to use Protoquill as part of the ZIO service (https://zio.dev/reference/service-pattern/introduction/), just as I did with Quill for Scala 2. However, I have a compilation problem, which is probably due to a macro or inline function (I have not experienced this problem, using Quill).

Before I extend the trait, which is a ZIO service, everything works as expected, example code, which works:

private case class UserRepositoryDoobiePostgres() extends BasePostgresRepository {
  import doobieContext.*

  inline def xxxx(userEntity: UserEntity) = run(quote(users.insertValue(lift(userEntity))))

  inline def createUser(user: User): ZIO[Connection, DbException, User] = for {
    now <- Clock.instant
    entity = UserEntity(user.id.value, user.email.toString, now)
    _ <- tzio(run(quote(xxxx(entity))))
  } yield user

  inline def users = querySchema[UserEntity](UserRepository.Tables.users)

}

But if I extend the trait, like (changed extends, and addred override):

private case class UserRepositoryDoobiePostgres() extends UserRepository with BasePostgresRepository {
  import doobieContext.*

  inline def xxxx(userEntity: UserEntity) = run(quote(users.insertValue(lift(userEntity))))

  inline override def createUser(user: User): ZIO[Connection, DbException, User] = for {
    now <- Clock.instant
    entity = UserEntity(user.id.value, user.email.toString, now)
    _ <- tzio(run(quote(xxxx(entity))))
  } yield user

  inline def users = querySchema[UserEntity](UserRepository.Tables.users)

}

I received the following compilation error:

error] 37 |  inline override def createUser(user: User): ZIO[Connection, DbException, User] = for {
[error]    |                                                                                   ^

I can also set methods as inline in trait, but this will require that almost the entire application has inline functions. I wonder if it's possible to limit this to just the database part.

Hi @PawelJ-PL, wondering if you came to a solution here?

[PawelJ-PL]

Yes, I found solution. As I remember, i fixed it by importing import io.getquill.* or importing quill methods from context (I can't remember, but I fixed it using proper import)
