Rust Code Quality Review

Systematically review Rust code quality against best practices.

Quality Dimensions

Analysis Commands

# Project structure
find . -name "*.rs" -not -path "*/target/*" -exec wc -l {} + | sort -rn

# Error handling
rg "unwrap\(\)" --glob "!*/tests/*" --glob "*.rs"

# Async patterns
rg "async fn|spawn_blocking|tokio::" --glob "*.rs"

# Testing
cargo test --all
cargo tarpaulin --out Html

# Linting
cargo fmt -- --check
cargo clippy --all -- -D warnings
cargo audit
