Enum FlowNode 

#[non_exhaustive]
pub enum FlowNode {
    Step(Box<StepNode>),
    Decision(DecisionNode),
    Split(Box<SplitNode>),
    Join(JoinNode),
    PartitionedStep(Box<PartitionedStepNode>),
}

One node of a declared flow graph.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Step(Box<StepNode>)

A tasklet or chunk step.

Decision(DecisionNode)

A deterministic decision.

Split(Box<SplitNode>)

A bounded set of linear branches and its structural join.

Join(JoinNode)

A structural join owned by exactly one split.

PartitionedStep(Box<PartitionedStepNode>)

A bounded durable local-partition manager.
