Documentation Improvement Ideas

This chapter is a roadmap for the next iteration of the book. Each subsection summarises a gap we discovered while reviewing the crate and outlines the minimal content that would help readers apply the feature in practice. When you pick one of these items up, try to produce a runnable example (or at least executable pseudocode) so the section teaches a concrete workflow rather than a theory sketch.

High-priority topics

The following themes unblock common deployment or operational scenarios and should be tackled first when planning documentation work:

Remote object stores

repo::objectstore::ObjectStoreRemote::with_url wires the repository into object_store services such as S3, local filesystems or Azure storage. The future chapter should walk through credential configuration, namespace selection, and pairing the remote backend with other stores (for example via HybridStore). It also needs to call out how branch updates rely on PutMode::Update/UpdateVersion retries, how conflicts bubble up to callers, and how listings stream through BlockingIter so readers know what consistency guarantees to expect. 【F:src/repo/objectstore.rs†L108-L316】

Hybrid storage recipes

repo::hybridstore::HybridStore mixes a blob store with a separate branch store. Documenting a few reference layouts—remote blobs with local branches, piles with in-memory branches, or even two-tier caches—will help teams evaluate trade-offs quickly. 【F:src/repo/hybridstore.rs†L1-L86】

Signature verification

Both repo::commit::verify and repo::branch::verify expose helpers for validating signed metadata before accepting remote history. A hands-on example should explain when to perform verification, how to surface failures to callers, and which key material needs to be distributed between collaborators. 【F:src/repo/commit.rs†L84-L122】 【F:src/repo/branch.rs†L95-L136】

Repository migration helpers

repo::transfer rewrites whichever handles you feed it and returns the old and new identifiers so callers can update references. A migration recipe could show how to collect handles from BlobStoreList::blobs() for full copies or from reachable when only live data should be duplicated. Highlight how the helper fits into a scripted maintenance window. 【F:src/repo.rs†L394-L516】

Conservative GC tooling

The garbage-collection chapter covers the high-level approach, but it should also reference concrete APIs such as repo::reachable, repo::transfer, and MemoryBlobStore::keep. Describing how to compute and retain the reachable set in code makes it easier to embed the GC workflow into automated jobs. 【F:src/repo.rs†L394-L516】 【F:src/blob/memoryblobstore.rs†L169-L210】

Emerging capabilities

These topics are less urgent but still deserve coverage so that readers can reuse advanced building blocks without digging through source code.

Succinct archive indexes

blob::schemas::succinctarchive::SuccinctArchive converts a TribleSet into compressed wavelet matrices, exposes helpers such as distinct_in and enumerate_in, implements TriblePattern, and serialises via ordered, compressed or cached Universe implementations. A dedicated section should walk through building an archive from a set, choosing a universe, storing it as a blob, and querying it directly through SuccinctArchiveConstraint so readers can reuse the on-disk index without round-tripping through TribleSet conversions. 【F:src/blob/schemas/succinctarchive.rs†L100-L529】 【F:src/blob/schemas/succinctarchive/universe.rs†L16-L265】 【F:src/blob/schemas/succinctarchive/succinctarchiveconstraint.rs†L9-L200】

Extensible path engines

Regular path queries run through RegularPathConstraint, which delegates edge checks to the PathEngine trait. The book should document how the built-in ThompsonEngine constructs NFAs from a TribleSet and demonstrate how to plug in alternative engines backed by other graph stores so readers can extend the regex-based traversal beyond in-memory datasets. 【F:src/query/regularpathconstraint.rs†L1-L200】

How to keep this list fresh

Treat these notes as a living backlog. Whenever a new subsystem lands, ask yourself whether it needs a discoverability guide, a tutorial or a troubleshooting section. Update this chapter with the gaps you observe, and link to the relevant modules so future contributors can jump straight into the implementation.
