Data Structure Memory Footprint Estimator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

A zero-sized element makes the overhead percentage undefined through division by zero, and the unspecified unit convention for element_size can change the result substantially.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "structure_type": "array",
    "element_count": 1000,
    "element_size_bytes": 8,
    "pointer_width": "64-bit"
  },
  "expected_outputs": {
    "estimated_total_memory_bytes": 8000,
    "overhead_percentage": 0
  },
  "working": "Raw data = n × element_size = 1000 × 8 = 8000 bytes. Array total = n × element_size = 1000 × 8 = 8000 bytes. Overhead = 8000 - 8000 = 0 bytes. Overhead percentage = 0 / 8000 × 100 = 0%."
