Module surface 

Public API surface from rustdoc JSON: item paths, span-derived fingerprints, doc presence, and literal source signatures.

Fingerprints hash the item’s source span text (ordinary comments stripped, then whitespace-normalized), not rustdoc’s structured types — rustdoc item ids shift across builds and would churn a structure-based hash.

Structs

ItemGroup

One distinct item, grouped by (kind, fingerprint) to collapse the extra path keys alias_reexports adds for the same underlying function — representative is the shortest path (for display), aliases holds every spelling (for lookups, since a covers= tag may name any of them). Un-fingerprinted items (span unreadable) are never merged with others.

ItemInfo

What the surface records about one public item — enough to detect any change to it (fingerprint), classify the change (signature), and audit coverage (kind, has_docs).

Surface

Public items keyed by full path (crate::module::item).

Functions

from_rustdoc

Build a surface from a rustdoc JSON document. source_root resolves the relative filenames in spans (the directory rustdoc ran in).
