Rust theory
Ownership, borrow checker, fearless concurrency, and SBF internals.
Practise in the Code Lab →Easy
- 1. Installing Rust and Cargorustup, cargo and the anatomy of a crate.
- 2. Variables and Mutabilitylet bindings are immutable by default.
- 3. Scalar TypesIntegers, floats, bool and char.
- 4. Tuples, Arrays and SlicesFixed-size compound types.
- 5. Functions and ExpressionsRust is an expression language.
- 6. Control Flowif, loop, while and for.
- 7. OwnershipEvery value has exactly one owner.
- 8. BorrowingReferences read data without owning it.
- 9. Stack and HeapWhere values live.
- 10. String and &strTwo string types and why.
- 11. StructsNamed product types.
- 12. EnumsSum types that carry data.
- 13. Pattern Matchingmatch, if let and while let.
- 14. Option<T>Rust's answer to null.
- 15. Result<T, E>Recoverable errors as values.
- 16. VectorsGrowable arrays.
- 17. HashMap and HashSetKey-value and unique-set storage.
- 18. IteratorsLazy, zero-cost pipelines.
- 19. Modules and Visibilitymod, pub and use.
- 20. Testing and Documentationcargo test, doc tests and clippy.
Medium
- 21. GenericsWrite once, monomorphise for each type.
- 22. TraitsShared behaviour contracts.
- 23. Trait Objects and dynStatic versus dynamic dispatch.
- 24. LifetimesNaming how long references are valid.
- 25. Smart Pointers: Box, Rc, RefCellHeap allocation and shared ownership.
