# Rust Development > Guidelines for Rust development in the ApexStore project — build commands, code conventions, LSM-tree architecture, and project structure. Use when this capability is needed. - Skill: `tomevault-io/rust-development-2` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/rust-development-2` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/rust-development-2/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/rust-development-2 --- # Rust Development Skill ## Build & Test Commands ```bash cargo build --release # production build cargo test --all-features # run all tests cargo clippy --all-targets --all-features -- -D warnings # lint cargo fmt --all -- --check # formatting check cargo doc --no-deps --all-features # documentation cargo audit # security audit cargo bench # benchmarks ``` ## Project Structure - `src/lib.rs` — library root, re-exports - `src/core/` — storage engine (memtable, sstable, compaction, WAL, block_cache, merge_iterator, column_family) - `src/api/` — HTTP API (actix-web routes, handlers, models) - `src/cli/` — CLI interface (clap) - `src/tui/` — Terminal UI (ratatui) - `benches/` — Criterion benchmarks - `tests/` — Integration tests ## Code Conventions - `thiserror` for library errors, `anyhow` for binaries - `?` operator for error propagation (never `unwrap()` in production) - Explicit lifetimes when needed, not by default - Unit tests in same file with `#[cfg(test)]` - Integration tests in `tests/` directory ## LSM-Tree Architecture - Writes → Memtable (WAL + skiplist) → flush → SSTable L0 - Compaction merges SSTables across levels - Bloom filters accelerate point reads - Block cache (LRU) caches deserialized data blocks - MergeIterator merges multiple sorted iterators --- > Source: [ElioNeto/ApexStore](https://github.com/ElioNeto/ApexStore) — distributed by [TomeVault](https://tomevault.io).
