Module capture 

Runtime reader for the ironprint.json fingerprint embedded in the binary.

The companion build module (feature dependency-graph-build) writes ironprint.json to $OUT_DIR at compile time. The downstream binary embeds it with:

const IRONPRINT: &str = include_str!(concat!(env!("OUT_DIR"), "/ironprint.json"));

Functions

• parse — deserialises the embedded JSON into a typed IronprintData struct. Returns CaptureError if the JSON is malformed or a required section is absent.
• as_bytes — returns the raw JSON bytes. Because the JSON is normalised and sorted at build time, the returned bytes are stable and deterministic across equivalent builds.

Concerns

• The data is a read-only snapshot fixed at compile time. It reflects the build environment at the time of compilation, not the current runtime state.
• The fingerprint resides as plain text in the binary’s read-only data section. It is neither encrypted nor obfuscated and is visible to anyone with access to the binary.
