final def &![Fx2 <: HasSignature](fx2: Fx2): Combine2[CyclicMemoizer[K, V], Fx2]

Combines with another Effect instance, so that a single Handler for 2 effects can be created.

final def perform[A, U <: ThisEffect](f: CyclicMemoizerSig[K, V] & Signature { type ThisEffect = U; } => A !@! U { def apply(z: CyclicMemoizerSig[K, V] & Signature { type ThisEffect = U; }): A !@! U; }): Computation[A, U]

Lifts an invocation of this Signature's method into the Computation monad.

Lifts an invocation of this Signature's method into the Computation monad.

The purpose of perform is similar to:

  • send function form various effect systems (Eff monad, etc.)
  • serviceWith from ZIO 1.x.
  • serviceWithZIO from ZIO 2.x.

⚠️ Scaladoc displays the definition of perform as more complex than it actually is:

final def perform[A, U <: ThisEffect](f: (z: Z & Signature { type ThisEffect = U }) => z.!@![A, U]): A !! U
