01 · Foundations02 · Applied03 · Concurrent & Async04 · Web Full-Stack05 · Systems & Advanced06 · The SourceProve the toolchain works: your first program compiles and greets you back.01 · T0Hello, RustImmutable by default is not a restriction; it is the first safety rail.01 · T1Variables and TypesAlmost everything is an expression: in Rust, even an if has a value.01 · T2Functions & Control FlowOne owner per value: the rule that deletes the garbage collector.01 · T3OwnershipLend a value without giving it away, and let the compiler referee.01 · T4Borrowing & ReferencesWhy Rust has two string types, and when a view beats a copy.01 · T5Slices and StringsModel your domain so illegal states refuse to compile.01 · T4Structs and Enumsmatch makes you handle every case; forgetting one is a compile error.01 · T5Pattern MatchingNo exceptions, no null: failure is data you are forced to look at.01 · T6Errors as ValuesThe standard collections, and what ownership means for what goes in them.01 · T5Vec, HashMap & FriendsWrite it once for every type, and pay nothing at runtime.01 · T5GenericsShared behavior without inheritance: the interface everything else builds on.01 · T6TraitsName how long references live: the borrow checker's final boss.01 · T6Lifetimescargo, clippy, rustfmt, rustdoc: the tooling other languages wish they shipped with.02 · T1Cargo & the ToolchainCarve a codebase into pieces with visibility the compiler enforces.02 · T5Modules & WorkspacesTests live next to the code, run with one command, and double as documentation.02 · T7TestingChains of map and filter that compile down to the loop you would have written by hand.02 · T7Closures and IteratorsWhen ownership needs to bend: heap allocation, shared owners, interior mutability.02 · T7Box, Rc, RefCellShip a real command-line tool: args, files, errors, and a release binary.02 · T8Build a CLISpawn real OS threads and let ownership stop the data races before they exist.03 · T8ThreadsDo not communicate by sharing memory; share memory by communicating.03 · T9ChannelsShared mutable state, made honest: the lock is part of the type.03 · T9Arc and MutexTwo invisible traits decide what may cross a thread boundary.03 · T10Send and SyncConcurrency without threads: futures that do nothing until polled.03 · T8async / awaitThe async runtime: tasks, timers, IO, and what spawn really requires.03 · T11TokioOne derive turns your types into JSON and back, with errors caught at the boundary.04 · T7SerdeHTTP handlers are plain async functions; extractors are just types.04 · T12AxumSQL checked against a live schema at compile time: a typo'd column is a build error.04 · T12SQLx and PostgresFine-grained reactive UI in Rust, rendered on the server, hydrated in wasm.04 · T13LeptosOne annotated function, callable from the browser, type-checked end to end.04 · T14Server FunctionsDocker, Fly, and a CI gate: git push becomes the deploy button.04 · T15Ship ItThe escape hatch with a contract: what unsafe permits, and what it never excuses.05 · T8Unsafe RustCall C and be called by C: Rust at the boundary where the guarantees end.05 · T9FFICode that writes code, pattern-matched at compile time.05 · T6macro_rules!The machinery behind derive: parse a syntax tree, emit Rust.05 · T7Procedural MacrosMeasure first: flamegraphs, benchmarks, and where zero-cost is literal.05 · T8Performance & ProfilingCompile Rust for the browser and meet the other half of this very site.05 · T7WebAssemblyRead the main.rs that served you this page: router, SSR shell, context injection.06 · T16The ServerThe completion counter you clicked, traced from form post to Postgres row.06 · T17The Data LayerVoyage embeddings, Qdrant, Claude: the tutor's entire pipeline, in Rust.06 · T17The RAG Tutorbuild.rs as quality culture: rendered markdown, the vocabulary gates, graph validation, verified examples.06 · T18The Build Gauntlet
