Enum LoopCondition 

#[non_exhaustive]
pub enum LoopCondition {
    BodyTerminal,
    WhenSignaled(NodeId),
    Exhaust,
}

What ends a loop.

The compiler resolves this to a concrete form before the executor sees it, so at runtime there is never a question of which node decides.

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.

BodyTerminal

Resolve at compile time to the body’s single terminal node — the one no other body node depends on. Compilation fails if the body has more than one, rather than picking whichever finished last.

This is the default for Node::loop_node.

WhenSignaled(NodeId)

Stop when the named node’s output signals completion.

Exhaust

Ignore signals; run the body exactly max_iterations times.
