From 89e17803d1d07206ba31e45aeb450fe263c5befa Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Aug 2026 15:10:25 +0000 Subject: [PATCH 1/3] Bump Rust 1.95.0 -> 1.97.1 (toolchain, CI, Dockerfiles) Operator-directed: bump now, fix after. rust-toolchain.toml, the CI MSRV/BLAS_MSRV/matrix pins, and both Dockerfiles move together. The Dockerfiles were installing 1.94.0 - a pre-existing drift BEHIND this repo's own 1.95.0 pin, so the images were building on an older toolchain than the workspace declared. They are now on 1.97.1 with the rest. (The drift-proof pattern, worth adopting later: COPY rust-toolchain.toml and use --default-toolchain none, as ruff's Dockerfile does, so the image can never disagree with the pin.) Toolchain verified clean on the CURRENT dependency pins before this bump - measured on the sibling lance-graph workspace, which path-deps this crate, with no new lint or language surface on 1.97.1. Workspace clippy here has NOT been re-run under 1.97.1; that is the fix-after. --- .github/workflows/ci.yaml | 24 ++++++++++++------------ Dockerfile | 12 ++++++------ Dockerfile.avx512 | 6 +++--- rust-toolchain.toml | 2 +- 4 files changed, 22 insertions(+), 22 deletions(-) diff --git a/.github/workflows/ci.yaml b/.github/workflows/ci.yaml index f2fbcab2..fe37abe5 100644 --- a/.github/workflows/ci.yaml +++ b/.github/workflows/ci.yaml @@ -21,8 +21,8 @@ env: # `LazyLock` detection means one binary, all ISAs.

Per the hard rule I stopped immediately after `cargo fmt` and did **not** run any further cargo invocations (no targeted `cargo test`, no additional clippy passes). All fixes above are comment/mechanical-only changes (`.clone()?` collapse, digit regrouping, literal substitution, `iter_mut().enumerate()`), so behavioural risk is low, but the orchestrator should re-run `cargo test -p ndarray` centrally once disk space is confirmed healthy. diff --git a/src/bitwise.rs b/src/bitwise.rs index 0d849dde..59639269 100644 --- a/src/bitwise.rs +++ b/src/bitwise.rs @@ -634,7 +634,8 @@ mod tests { #[test] fn test_popcount_batch_u64() { let words = [0xFFFFFFFFFFFFFFFFu64, 0, 0x0F0F0F0F0F0F0F0F]; - assert_eq!(super::popcount_batch_u64(&words), 64 + 0 + 32); + // per-word contributions: 64 + 0 + 32 + assert_eq!(super::popcount_batch_u64(&words), 96); } #[test] diff --git a/src/indexes.rs b/src/indexes.rs index 762815e0..b432b9c4 100644 --- a/src/indexes.rs +++ b/src/indexes.rs @@ -57,10 +57,7 @@ where type Item = D::Pattern; #[inline] fn next(&mut self) -> Option { - let index = match self.index { - None => return None, - Some(ref ix) => ix.clone(), - }; + let index = self.index.clone()?; self.index = self.dim.next_for(index.clone()); Some(index.into_pattern()) } diff --git a/src/iterators/mod.rs b/src/iterators/mod.rs index e35bacc3..1a731087 100644 --- a/src/iterators/mod.rs +++ b/src/iterators/mod.rs @@ -488,10 +488,7 @@ impl<'a, A, D: Dimension> Iterator for IndexedIter<'a, A, D> { type Item = (D::Pattern, &'a A); #[inline] fn next(&mut self) -> Option { - let index = match self.0.inner.index { - None => return None, - Some(ref ix) => ix.clone(), - }; + let index = self.0.inner.index.clone()?; match self.0.next() { None => None, Some(elem) => Some((index.into_pattern(), elem)), @@ -664,10 +661,7 @@ impl<'a, A, D: Dimension> Iterator for IndexedIterMut<'a, A, D> { type Item = (D::Pattern, &'a mut A); #[inline] fn next(&mut self) -> Option { - let index = match self.0.inner.index { - None => return None, - Some(ref ix) => ix.clone(), - }; + let index = self.0.inner.index.clone()?; match self.0.next() { None => None, Some(elem) => Some((index.into_pattern(), elem)), diff --git a/src/palette_codec.rs b/src/palette_codec.rs index 33683b4e..b1e39d85 100644 --- a/src/palette_codec.rs +++ b/src/palette_codec.rs @@ -807,8 +807,8 @@ mod tests { // Create states with a small palette let mut states = vec![0u16; 4096]; - for i in 0..4096 { - states[i] = (i % 4) as u16; + for (i, state) in states.iter_mut().enumerate() { + *state = (i % 4) as u16; } let mut palette = HashMap::new(); diff --git a/src/property_mask.rs b/src/property_mask.rs index 063b709e..0d02c76f 100644 --- a/src/property_mask.rs +++ b/src/property_mask.rs @@ -423,7 +423,7 @@ mod tests { assert!(m.test(0b1000)); // field = 10 => 2 assert!(!m.test(0b0100)); // field = 01 => 1 assert!(!m.test(0b1100)); // field = 11 => 3 - assert!(m.test(0b11111_1000)); // field still 10 + assert!(m.test(0b1_1111_1000)); // field still 10 } #[test] From f4be38abf9d7c83ac9b4550b33fdd4f02cb2b718 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Aug 2026 18:23:57 +0000 Subject: [PATCH 3/3] Declare the MSRV that CI actually tests: rust-version 1.95 -> 1.97 `rust-toolchain.toml` moved to 1.97.1 and CI's `MSRV` / `BLAS_MSRV` env are already 1.97.1, but `Cargo.toml` still declared `rust-version = "1.95"` and the toolchain comment still described the 1.95 rationale.
