io.getquill.context.qzio

Use to provide run(myQuery) calls with a context implicitly saving the need to provide things multiple times. For example in JDBC:

 case class MyQueryService(ds: DataSource with Closeable) {
   import Ctx._
   implicit val env = Implicit(Has(ds))

   val joes = Ctx.run(query[Person].filter(p => p.name == "Joe")).onDataSource.implicitly
   val jills = Ctx.run(query[Person].filter(p => p.name == "Jill")).onDataSource.implicitly
   val alexes = Ctx.run(query[Person].filter(p => p.name == "Alex")).onDataSource.implicitly
 }

Normally you would have to do a separate provide for each clause:

 val joes = Ctx.run(query[Person].filter(p => p.name == "Joe")).onDataSource.provide(Has(ds))
 val jills = Ctx.run(query[Person].filter(p => p.name == "Jill")).onDataSource.provide(Has(ds))
 val alexes = Ctx.run(query[Person].filter(p => p.name == "Alex")).onDataSource.provide(Has(ds))

For other contexts where the environment returned from run(myQuery) just the session itself, usage is even simpler. For instance, in quill-zio-cassandra, you only need to specify implicitly.

 case class MyQueryService(cs: CassandraZioSession) {
   import Ctx._
   implicit val env = Implicit(Has(cs))

   def joes = Ctx.run { query[Person].filter(p => p.name == "Joe") }.implicitly
   def jills = Ctx.run { query[Person].filter(p => p.name == "Jill") }.implicitly
   def alexes = Ctx.run { query[Person].filter(p => p.name == "Alex") }.implicitly
 }
