This lesson

This lesson teaches Production checklist: the syntax, APIs, and habits you need before advancing in Rust.

Teams ship Production checklist on every Rust codebase—skipping it leaves gaps in debugging and code reviews.

You will apply Production checklist in contexts like: Infrastructure CLIs, proxies, game engines, blockchain nodes, and latency-sensitive backends.

Write Rust with fn main(), click Run on server—the dev runner compiles main.rs with rustc and runs the binary; fix borrow errors from stderr (requires Rust toolchain; LEARNING_RUNNER_ENABLED=true).

When functions, arrays, and basic OOP from intermediate lessons are familiar.

Shipping Rust means more than compiling—configure releases, logging, metrics, CI, and dependency auditing.

Checklist

cargo build --release for optimized binaries
Structured logging (tracing, log)
cargo audit / deny for supply chain
Clippy and rustfmt in CI
Document unsafe invariants if any unsafe blocks exist

Important interview questions and answers

Q: How reduce binary size?
A: Release profile, strip symbols, LTO, avoid unused features in dependencies.

Self-check

Why run clippy in CI?
What does --release change?

Playground

Runs on the configured server runner (dev: npm run runner with LEARNING_RUNNER_ENABLED=true). Output appears below the editor.

Code runner not available

Server runner is disabled. Set LEARNING_RUNNER_ENABLED=true and LEARNING_RUNNER_URL in .env (see .env.example).
