Bump Rust toolchain pin from 1.97.1 to 1.98.1 - #47
Conversation
The pin previously lived only as prose (CLAUDE.md's `cargo +1.97.1` build commands, docs/WASM-INTEGRATION.md, scripts/build-graph-wasm.sh's RUST_TOOLCHAIN default) and in the two Dockerfiles' ARG RUST_VERSION — this repo has no .github/workflows to carry a pin either. Added rust-toolchain.toml (mirroring lance-graph's shape: channel + components + an append-only bump log) so a bare `cargo` in this checkout now resolves to the reviewed toolchain directly, closing the exact drift shape that let the prose pin fall behind the sibling repos. 1.98's only delta in this workspace: two `clippy::chunks_exact_to_as_chunks` findings (new in 1.98, default-on STYLE group), both in a2ui-graph test code, fixed to `.as_chunks::<N>().0`. No `#![allow]`/`#![expect]` list carried the removed `clippy::from_iter_instead_of_collect`. Verified on the real 1.98.1 toolchain: `cargo test` (79 tests, 0 failed), `cargo clippy --all-targets -- -D warnings` (clean), `cargo fmt --check` (clean).

📝 WalkthroughWalkthroughThe repository now pins Rust 1.98.1, updates related build documentation and scripts, and replaces two byte-slice test iterations with fixed-size chunk processing. ChangesRust toolchain alignment
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The Rust 1.98.1 alignment is validated, but the documented one-off WASM override currently names an unavailable toolchain, so users following that example cannot complete a preview build until the example is corrected.

This repo has never had any CI — .github/workflows/ did not exist, and PR #47's only check is Cursor Bugbot. Add .github/workflows/lint.yml with three jobs (format, clippy, test) using actions-rust-lang/setup-rust-toolchain, which reads rust-toolchain.toml directly so the pinned version stays in exactly one place. All of this repo's OGAR dependencies (ogar-a2ui-frame, ogar-render-askama, ogar-encryption, ogar-vocab) are git deps pinned to branch = "main", per Cargo.toml's own comment ("this repo has no sibling checkout ... and no CI to arrange one") — so no sibling checkout step is needed; cargo fetches them directly in the CI runner. Also update CLAUDE.md's three build-gate lines to drop the explicit `cargo +1.97.1 ...` prefix (stale since the 1.98.1 bump, and a second source of truth for the toolchain version regardless of which number it names) — a bare `cargo` in this checkout already resolves to the pin in rust-toolchain.toml.

Use an available toolchain in the override example.
The 1.99.0 channel is unavailable, so RUST_TOOLCHAIN=1.99 can fail in both the target check and cargo "+$TOOLCHAIN". Use RUST_TOOLCHAIN=beta for a preview build.
Proposed documentation fix
-# Override for a one-off: `RUST_TOOLCHAIN=1.99 ./scripts/build-graph-wasm.sh`.
+# Override for a one-off preview build: `RUST_TOOLCHAIN=beta ./scripts/build-graph-wasm.sh`.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
rust-toolchain.tomland no.github/workflows/— the pin previously existed only as prose: CLAUDE.md'scargo +1.97.1 test/clippy/fmtbuild commands,docs/WASM-INTEGRATION.md,scripts/build-graph-wasm.sh'sRUST_TOOLCHAINdefault, and the two Dockerfiles'ARG RUST_VERSION.rust-toolchain.toml, mirroring the shape used by every sibling repo in this stack (lance-graph,OGAR,tesseract-rs,stockfish-rs,ruff) — channel +components = ["rustfmt", "clippy"]+ an append-only bump-log comment, with the version stated only once (inchannel) so future bumps don't leave stale prose behind. This is exactly the drift shape that let this repo's pin diverge from its siblings in the first place. If the team prefers to keep this repo prose-only, this file is easy to drop from the PR.clippy::chunks_exact_to_as_chunks(new in 1.98, default-on STYLE group) fired at two test-only call sites ina2ui-graph(radial.rs,gpu.rs); both rewritten to.as_chunks::<N>().0.
