Overview

Kickstart your journey into Rust's functional world with this hands-on guide. You'll learn to think in pure functions, model domains with algebraic data types, and compose zero-cost abstractions, building the confidence to create safe, concurrent, and maintainable applications from day one. What You'll Learn - Embrace pure functions and side-effect isolation using Result, Option, and functional error pipelines - Model complex domains with structs and enums, capturing business invariants in ADTs - Harness exhaustive pattern matching and advanced destructuring to handle every case at compile time - Build custom error types and chain failures elegantly with the ? operator and combinators - Design zero-cost abstractions via generics, monomorphization, and traits as type-classes - Master lazy, composable iterator chains and craft your own iterator adaptors for efficient data flows - Leverage async/await and futures for non-blocking I/O, then offload CPU-bound work to Rayon's parallel iterators - Navigate Rust's concurrency guarantees with Send and Sync, scoped thread pools, and safe shared state - Encapsulate side effects in adapter layers-keeping your core logic pure and fully testable - Test, benchmark, and validate: unit tests, property-based tests, integration tests, and Criterion benchmarks Hands-On Projects - Split a CLI into two crates-pure core logic and I/O adapter-proving zero side-effects in tests - Build an AST for a mini expression language, implement a fold-style evaluator and precedence-aware pretty-printer - Develop an in-order iterator for a generic binary tree plus an in-place map_tree function with zero heap allocations - Create an async pipeline that fetches JSON from multiple endpoints, validates payloads, and transforms data in parallel with Rayon - Construct a mini-service crate exposing pure request/response APIs, wrap it with a Tokio-powered adapter, and trace every call - Implement custom error-handling pipelines, leveraging thiserror and structured logging for clear diagnostics Who This Book Is For - Rust developers moving from imperative to functional styles, eager to harness purity and ADTs - Systems engineers building concurrent services without sacrificing safety or performance - Library authors crafting zero-cost abstractions and domain-specific APIs that are easy to test and evolve - Students and self-learners seeking a practical, project-driven path through Rust's functional programming features Take the first step toward mastering functional Rust. Design systems that are safe by construction, data flows that scale on multi-core machines, and codebases that remain clear, testable, and resilient over time.
