# 식별 가능한 유니온

> **이 문서는 [[Discriminated Unions]] 의 중복본입니다.** Canonical 문서로 redirect.

## 핵심 요약 (specialization aspects)
- 매 TypeScript discriminated union = literal `kind`/`type` field 매 union members 구별.
- 매 exhaustive matching via `switch` + `never` assertion. 매 ts-pattern library 매 advanced cases.
- 매 use cases: Result/Either, async state (idle/loading/success/error), event handlers, Redux actions.

## 🔗 Graph
- 부모: [[Discriminated Unions]] (canonical)
- 변형: [[Tagged Unions]] · [[Sum Types]]
- Adjacent: [[Pattern Matching]] · [[ts-pattern]] · [[Type Guards]]
