0013.5 가볍게 정리한 러스트 언어 특징들 🦀

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
