rust-toolchain.toml

[toolchain]
channel = "1.97.1"
# Pinned to 1.97.1 (2026-08-05). Aligns ndarray with the rest of the
# AdaWorldAPI stack — lance-graph, OGAR, ruff, MedCare-rs, woa-rs, a2ui-rs and
# stockfish-rs are all on 1.97.1; ndarray was the last sibling still declaring
# 1.95, so a consumer path-dep'ing both it and lance-graph-contract saw two
# different MSRVs.
#
# The channel here and `Cargo.toml`'s `rust-version` must move TOGETHER. They
# were out of step between the 1.95 → 1.97.1 channel bump and 2026-08-05: this
# file said 1.97.1 while the manifest still declared 1.95, and the comment below
# still described the 1.95 rationale. A stale comment on a version pin is how the
# next reader learns the wrong number.
#
# (Historical: the 1.95 bump introduced `clippy::manual_checked_ops`, which fired
# on `impl_owned_array.rs::into_scalar` and was fixed in that same commit.)
# Never auto-track `stable` — bump explicitly when a future version is
# reviewed and the workspace clippy passes clean.
