ci: fix Clippy, Rustfmt, and Typos failures for Rust 1.95 stable

[glaziermag]

Summary

Fixes CI failures introduced by #2109 (fast CUDA MMQ GGUF kernels) merged on 2026-04-15, combined with new lints in Rust 1.95 stable.

CI has been red on master since #2109 was merged. Every PR targeting master inherits these failures because CI merges the PR branch into current master.

Changes

Typos

• Exclude vendored mistralrs-quant/kernels/mmq_gguf/ directory
• Add CU_DEVICE_ATTRIBUTE_MAX_SHARED_MEMORY_PER_BLOCK_OPTIN to ignore list

Rustfmt (1.95)

• Fix import ordering in openapi_doc.rs
• Reformat lines affected by other lint fixes

Clippy (1.95)

• useless_conversion: remove redundant .into_iter() in zip/extend calls across tool_dispatch, rag, llava, idefics3, gemma4, distributed/layers
• iter_kv_map: use .into_values().flatten() in default_scheduler
• manual_checked_ops: use .checked_div() in distributed/layers, video.rs, pyo3/util.rs
• let_unit_value: remove unit let binding in bench.rs
• dead_code: allow unused num_experts field in MoEExperts (set but not yet read)

Validation Result

Validation, 2026-05-14: ACTUAL, FEASIBLE_NOW.

Environment:

• GPU validation environment
• Rust 1.95.0 (59807616e 2026-04-14)
• Typos 1.46.1

Base commit tested: 2d4ba4f16f61e5e18be085d0dd137bc95cba038a

cargo fmt --all -- --check
typos --config .typos.toml
cargo clippy --workspace --tests --examples -- -D warnings

Base result: all three failed. Rustfmt failed import ordering in mistralrs-server-core/src/openapi_doc.rs; typos failed on CUDA MMQ GGUF kernel terms; clippy failed two useless_conversion lints and one manual_checked_ops lint in mistralrs-quant/src/distributed/layers.rs.

PR head tested: 0a11bf2d931d76f7440c9ac24bc874fc69ba0134

Same commands all passed cleanly:

cargo fmt --all -- --check
typos --config .typos.toml
cargo clippy --workspace --tests --examples -- -D warnings

This is ACTUAL before/after validation for the Rust 1.95 CI/lint failures. GPU behavior is not material for this PR; the A100 machine was only the requested validation host.

Wave 1 evidence bundle update:

PR: #2115
Linked issue: CI failures after #2109
Base SHA: 2d4ba4f16f61e5e18be085d0dd137bc95cba038a
Current PR-head SHA: 0a11bf2d931d76f7440c9ac24bc874fc69ba0134
Fixed-head SHA, if changed: N/A

Exact commands recorded in the PR body:

cargo fmt --all -- --check
typos --config .typos.toml
cargo clippy --workspace --tests --examples -- -D warnings

Environment: GCP a2-highgpu-1g A100 host used as cloud validation host, Rust 1.95.0 (59807616e 2026-04-14), Typos 1.46.1; GPU behavior is not material.
A100 category: A100_HOST_OPTIONAL.
Base result: all three commands failed on base; rustfmt import ordering, typos CUDA MMQ GGUF kernel terms, and clippy useless_conversion / manual_checked_ops failures.
Current PR-head result: same commands passed cleanly.
Tests added/changed: lint/fmt/typos cleanup across the listed Rust files and .typos.toml.
Tests passed: fmt, typos, clippy on Rust 1.95 per PR body.
Side-effect controls: lint-only/format-only; no runtime or GPU behavior claim.
Raw logs/artifacts: PR body contains command list and pass/fail summary; no separate raw log file is attached in this comment.
Remaining risks: standalone raw command logs are still useful if reviewers require downloadable artifacts.
Can say “Fixes #issue”: yes for Rust 1.95 fmt/typos/clippy CI failures introduced after #2109.
Safe wording: “Fixes Rust 1.95 fmt/typos/clippy CI failures introduced after #2109.”
Readiness status: ready-now if PR-body log excerpts are accepted; otherwise standalone raw lint logs remain to attach.
