Verification Loop (Rust)

When to Use

• After completing a feature or significant code change
• Before creating a PR
• After refactoring
• When you want to ensure all quality gates pass

Verification Phases

Phase 1: Build Verification

cargo check 2>&1 | tail -20

If build fails, STOP and fix before continuing.

Phase 2: Format Check

cargo fmt -- --check 2>&1 | head -20

If formatting issues found, run cargo fmt to fix.

Phase 3: Lint Check

cargo clippy -- -D warnings 2>&1 | head -30

All clippy warnings are errors in this project. Fix before continuing.

Phase 4: Test Suite

# Run all tests with nextest
cargo nextest run 2>&1 | tail -50

# Also run doc tests (nextest doesn't run these)
cargo test --doc 2>&1 | tail -20

Report:

• Total tests: X
• Passed: X
• Failed: X

Phase 5: Coverage Check

cargo llvm-cov --summary-only 2>&1 | tail -10

Target: 85%+ coverage. If below threshold, identify uncovered code.

Phase 6: Security Audit

cargo audit 2>&1 | tail -20

Phase 7: Diff Review

git diff --stat
git diff HEAD --name-only

Review each changed file for:

• Unintended changes
• Missing error handling (.unwrap(), direct indexing)
• Files exceeding 500-600 line guideline
• Missing tests for new code paths

Output Format

After running all phases, produce a verification report:

VERIFICATION REPORT
==================

Build:     [PASS/FAIL]
Format:    [PASS/FAIL]
Clippy:    [PASS/FAIL] (X warnings)
Tests:     [PASS/FAIL] (X/Y passed)
Doc Tests: [PASS/FAIL]
Coverage:  [X%] (target: 85%)
Audit:     [PASS/FAIL] (X advisories)
Diff:      [X files changed]

Overall:   [READY/NOT READY] for PR

Issues to Fix:
1. ...
2. ...

Quick Verification (Pre-commit)

For fast checks during development:

just ci-check

This runs the project's standard CI validation suite.

Full CI Verification

Matches what runs in GitHub Actions:

cargo fmt -- --check && cargo clippy -- -D warnings && cargo nextest run && cargo test --doc && cargo audit
