Crate cadvm_core 

cadvm-core — the version-control engine for cadvm.

This crate owns the repository model: commits, manifests, refs, branches and HEAD, plus the operations over them (snapshot, status, diff, checkout, switch, revert, gc). It is deliberately UI-free — all terminal formatting lives in cadvm-cli.

Everything here is pure Rust. There is no geometry, no CAD kernel and no FFI; STEP files are treated as opaque text with light metadata scanning (see step).

Modules

checkout

Working-tree mutation: checkout, switch and revert.

config

Repository configuration (.cadvm/config.json) and author resolution.

diff

Manifest-level diffs (added / removed / modified files + metadata deltas).

error

Error type shared across cadvm-core.

format

Supported CAD file formats.

gc

Garbage collection: drop objects unreachable from any ref.

geom

Bridge to the cadvm-geom C++/OCCT helper (Step 2: geometric diff).

ignore

.cadvmignore support: a small, dependency-free pattern matcher.

index

Working-tree hash cache (.cadvm/index.json).

mesh

Lightweight metadata for triangle-mesh formats (STL, OBJ).

meshdiff

Mesh-based geometric diff for STL/OBJ — pure Rust, no Open CASCADE.

model

Core data types: commits, manifests and file entries.

repo

The Repository handle: on-disk layout, refs, HEAD and object I/O.

revision

Revision resolution: HEAD, HEAD~N, branch names, full and short hashes.

snapshot

Creating snapshots (commits) from the working tree.

status

Working-tree status: compare the working tree against a manifest.

step

Lightweight, textual analysis of STEP/STP files.

verify

Geometric verification: assert that a diff matches expectations.

worktree

Working-tree scanning helpers (find tracked-format files, hash them).

Structs

BlobRef

How a tracked file is laid out in the store: the whole-file raw hash plus the ordered list of fixed-size chunks that reconstruct it.

ChunkRef

A reference to a stored chunk: its hash plus where it sits in the source file.

ObjectId

A content-addressed object identifier (blake3:<hex>).

Store

A content-addressed object store rooted at a .cadvm/objects directory.

Enums

Category

The kind of object being stored. Each maps to a sub-directory under <objects>/.
