Struct InputDef 

pub struct InputDef {
    pub name: String,
    pub default: Value,
    pub port_type: PortType,
    pub kind: InputKind,
}

Definition of a named input to the Polydat graph.

All inputs — coordinates, iteration externs, and external-write ports — are defined uniformly. Coordinates default to Value::U64(0), captures default to Value::None (unset until a capture writes to them) or to their declared default. The kind field carries the lifecycle classification used by the init-binding contract (see SRD 11 §“Init Binding Contract”).

Fields

name: String

Input name (e.g., “cycle”, “username”).

default: Value

Default value. Coordinates default to U64(0), captures to their declared default (or None if unset).

port_type: PortType

The declared port type for this input. Used by the assembler for type checking when wiring nodes to this input.

kind: InputKind

Lifecycle classification. The assembler’s coordinate inputs are Coordinate; the DSL compiler sets IterationExtern for iteration externs and ExternalWrite for extern ports.

Trait Implementations
