Version: 1.0.18


ZIO already provided 5 build-in services, when we use these services we don't need to provide their corresponding environment explicitly. The ZEnv environment is a type alias for all of these services and will be provided by ZIO to our effects:

  • Console — Operations for reading/writing strings from/to the standard input, output, and error console.
  • Clock — Contains some functionality related to time and scheduling.
  • Random — Provides utilities to generate random numbers.
  • Blocking — Provides access to a thread pool that can be used for performing blocking operations.
  • System — Contains several useful functions related to system environments and properties.
