Field

Field extracts a named member of a composite value.

Behavior

y[n] = u[n].field. Selection adds no state or delay. The field must exist in the input’s composite type; the output keeps that field’s declared type.

Ports

Direction	Type	Meaning
Input	Selected composite type	Value containing the field.
Output	Selected field’s type	The field value, which may itself be a composite or array.

Parameters

Parameter	Type	Default	Meaning
field	Field name	Empty	Member to extract; select a valid field before use.
Type (editor)	Composite type	Empty	Composite whose fields the editor offers.

Example

For Measurement { value: f64, valid: bool }, selecting valid from Measurement { value: 12.5, valid: true } outputs the Boolean true.

Use Pack to construct a composite.
