trait Basic[+F[_], A] extends Lifecycle[F, A]
A sub-trait of izumi.distage.model.definition.Lifecycle suitable for less-complex resource definitions via inheritance that do not require overriding izumi.distage.model.definition.Lifecycle#InnerResource.
final class BufferedReaderResource( file: File ) extends Lifecycle.Basic[IO, BufferedReader] { def acquire: IO[BufferedReader] = IO { new BufferedReader(new FileReader(file)) } def release(reader: BufferedReader): IO[BufferedReader] = IO { reader.close() } }
