Books (recommended order)

1. The Rust Programming Language — Klabnik & Nichols. Free online; the default starting point.
2. Rustlings + small projects — see Practice below.
3. Rust for Rustaceans — Jon Gjengset. Lifetimes, traits, async, unsafe; best after you can write basic programs.
4. Programming Rust, 2nd ed. — Blandy / Orendorff / Tindall. Strong on concurrency and the standard library.
5. Asynchronous Programming in Rust — official async book (see table above).
6. Rust Atomics and Locks — Mara Bos. Free at marabos.nl/atomics. Memory ordering when you hit threads/Arc/lock-free code.

Workflow while learning:

cargo new my_project
# edit src/main.rs or src/lib.rs
cargo build
cargo run
cargo test
cargo clippy -- -D warnings
cargo fmt

Tooling to install

# Toolchain
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup component add rustfmt clippy rust-analyzer rust-src

# Optional but useful
rustup toolchain install nightly   # for experiments / some crates
cargo install cargo-watch cargo-expand cargo-nextest
cargo install hyperfine            # CLI benchmarking

cargo commands you will use constantly

Command	Purpose
cargo new foo / cargo new --lib foo	New binary / library crate
cargo build [--release]	Compile (debug or optimized)
cargo run -- arg1 arg2	Build and run; args after -- go to your program
cargo test	Run #[test] and doctests
cargo clippy -- -D warnings	Lint; treat warnings as errors
cargo fmt	Format code
cargo doc --open	Build and open API docs for your crate
cargo expand	See macro-expanded code (after installing cargo-expand)
