final case class IAnd[-I, +LO, +RO, +E](left: Stage[I, LO, E], right: Stage[I, RO, E]) extends BinaryOperator[Stage[I, LO, E], Stage[I, RO, E], I, (LO, RO), E] with Product with Serializable

An independent binary operator that applies two stages to the same input and combines their outputs into a tuple.

Both left and right are always applied — unlike And, which skips right if left produces no output.

  • If both stages yield h8io.stages.Yield.Some, the result is h8io.stages.Yield.Some((leftOut, rightOut), mergedStatus, ...).
  • If either stage yields h8io.stages.Yield.None, the result is h8io.stages.Yield.None(mergedStatus, ...).

Statuses from both stages are merged with combine (i.e., leftStatus.combine(rightStatus)). The evolution pairs each branch's continuations symmetrically.

I

the shared input type (contravariant)

LO

the left output type (covariant)

RO

the right output type (covariant)

E

the error type (covariant)

left

the first stage

right

the second stage

    A stage that throws from here must have released its own resources first — see the Lifecycle section above.

    Returns this stage's Evolution without consuming an input.

    Returns this stage's Evolution without consuming an input.

    Called instead of apply whenever the stage takes part in a run but has nothing to process: the upstream yielded no output, or a binary operator excluded this branch. The evolution must be the one the stage would have returned had it run. Like apply, skip() may perform side effects — a decorator, for instance, may advance or release the inner stage it owns.
