Enum InputKind 

pub enum InputKind {
    Coordinate,
    IterationExtern,
    ExternalWrite,
}

Classification of a named input by its evaluation lifecycle.

See evaluation_model.md for the lifecycle classification. The init-binding contract uses this to decide whether a wire to an Input(idx) is effectively-const at scope-init time: IterationExtern slots count as effectively-const (rebound once per scope activation); Coordinate and ExternalWrite slots are dynamic and disqualify any init binding that reaches them.

Variants

Coordinate

Dimensional input declared by input (cycle: u64, ...: u64) — dynamic, reset every cycle.

IterationExtern

External slot populated by materialize_wiring_from_outer from an enclosing for_each / for_combinations clause — effectively-const for the duration of one scope activation.

ExternalWrite

External port declared by extern name: type = default — written by capture extraction during op execution; dynamic across cycle boundaries within a stanza.
