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. Defaults to Coordinate so existing call sites that construct InputDef directly (tests, legacy paths) keep their previous semantics. The DSL compiler sets this explicitly for iteration externs and external-write ports.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InputDef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
