첫 번째 장에서는 러스트의 타입 시스템에 대해 조언한다. 러스트의 타입 시스템은 다른 주류
언어보다 훨씬 표현력이 뛰어나며, 오캐멀
OCaml
이나 하스켈
Haskell
과 같은 학술 연구용

언
어와 비슷한 점이 많다.
러스트 타입 시스템의 핵심 중 하나인
enum
(이넘, 열거형) 타입은 다른 언어보다 표현력이 훨
씬 뛰어나며, 대수적 데이터 타입

도 지원한다.
이 장에서는 러스트에서 제공하는 기본 타입을 소개하고, 이를 조합하는 방식으로 프로그램의
의미를 정확히 반영한 데이터 구조를 만드는 방법을 설명한다. 이렇게 프로그램 동작을 타입
시스템에 인코딩하면 프로그램 오류를 런타임이 아닌 컴파일 타임에 걸러낼 수 있어서 오류를
찾는 데 드는 수고를 줄일 수 있다.
이번 장에서는 러스트의 표준 라이브러리에서 제공하는 데이터 구조 중에서도 특히 자주 사용
되는
Option
,
Result
,
Error
,
Iterator
에 대해서도 소개한다. 이런 표준 도구를 익혀 두면,
코드를 간결하고 효율적이면서 러스트답게 관용적으로

Rust
작성하는 데 도움 된다. 또한
러스트의 물음표 연산자를 사용하면 타입 안전성을 해치지 않으면서 오류를 간결하게 처리할
수 있다.
