Effect is a basic, home-made functional effect system with powerful errors.

A value of type Effect[A] is a description of a computation that can produce a value of type A, can fail with an error E, can fail unexpectedly with a Throwable or can be interrupted.

Effect has only one type parameter. Effect[A] is mentally equivalent to ZIO[Any, E, A] where error type E is fixed to the error model e.scala.E.

Effect is only a functional effect and not a complete solution to everything.

Add following to your build.sbt (for now, Scala 3 only):

libraryDependencies += "dev.akif" %% "effect-core" % "0.3.1"

Effect is built with SBT. So, standard SBT tasks like clean, compile and test can be used.

To run all tests:

sbt test

To run specific test(s):

sbt 'testOnly fullyQualifiedTestClassName1 fullyQualifiedTestClassName2 ...'
