0013.5 가볍게 정리한 러스트 언어 특징들 🦀

- 0013 Rust 🦀

• Returning a Reference to the Stack
• Mutable reference is a non Copy type
• derive attribute
• impl is not method, is associated function
• diff between const with static in rust
• Option의 unwrap 메서드는 소유권을 가져간다
• unsafe pointer
• From과 Into Trait를 사용하여 유연한 캐스팅 지원하기
• FromStr 을 구현하면 파싱을 공통적인 방법으로 수행할 수 있다고
• 자식 모듈은 부모 모듈의 private 요소들을 자유롭게 접근할 수 있다
• Multiple Patterns and match guards
• vector init with size, not capacity
• Ord is total order, PartialOrd is partial order
• single field struct, enum with repr transparent
• derivable traits and trait inheritance
• rc try_unwrap
• values in a scope are dropped in the opposite order they are defined
• thread safety with Arc which violates interior mutability
• is there a way to iterate through the values of an enum
• iterator skip
• idiomatic way to input from stdin when CP in rust
• idiomatic way to output to stdout when CP in rust
• slice patterns and destructure and refutability
• [[Blanket impl]]
• generic array in rust
• array_zip is unstable
• Negative bounds
• exception safety with rust
• Debug trait and DebugList builder and DebugStruct builder etc
• compare two iterators
• Hasher에게 먹이 주기 feed Hasher

• FromIterator를 구현하면 collect할 수 있다

  • Statements and Expressions
  • let 변수 선언만 해도 되나요
  • loop label
  • Box
  • immutable to mutable
  • Permission Handling
  • static lifetime
  • lifetime elision
  • Deref trait
  • immutable reference is copyable, mutable reference is not copyable
  • How to add between different types - rust
  • Using the Newtype Pattern to Implement External Traits on External Types
  • MIRI - Mid-level Intermediate Representaion Interpreter

• different with other languages like c c++

  • rust에서 c++와 같은 custom comparator를 정의할 수 있을까요
  • 오버로딩이 없다
  • Indexing is opaque
  • 러스트에서 인라인 정의
  • 모든 impl이 extension이고 모든 Trait들이 프로토콜이다
  • Strategy - Rust Design Patterns
