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

A binary operator that applies left and right to the same input sequentially, producing a tuple of both outputs when both succeed.

The evaluation is short-circuit on the left side:

  • If left yields h8io.stages.Yield.Some, right is applied to the same input.
    • If right also yields Some, the result is Yield.Some((leftOut, rightOut), ...).
    • If right yields None, the result is Yield.None(mergedStatus, ...).
  • If left yields h8io.stages.Yield.None, right is **not** applied and the result is Yield.None(leftStatus, ...).

Statuses from both sides are merged with combine.

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 to apply

right

the second stage to apply when left succeeds

    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.

    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.
