}

The combinator algebra terms.

Variants

Identity

Pass-through: returns the input as output.

Sequence(Vec<Combinator>)

All must succeed in order.

Parallel(Vec<Combinator>)

All must succeed (order-independent; we process left-to-right).

Choice(Vec<Combinator>)

First success wins.

Guard(Box<Combinator>, Predicate)

Proceed only if predicate holds.

Transform(Box<Combinator>, TransformFn)

Modify the result of the inner combinator.

Retry(Box<Combinator>, RetryPolicy)

Retry with policy.

Timeout(Box<Combinator>, Duration)

Deterministically budget-bounded reduction.

Checkpoint(Box<Combinator>, CheckpointId)

Resumable checkpoint.
