メモ scala のtype Aliasのアクセスの仕方

More than 3 years have passed since last update.
trait Fuge { 
  type A = String

Fuge.Aを見たい場合 普通にFuge.Aでアクセスする場合と Fuge#Aでアクセスする場合がある

  • traitなどの定義からアクセスする方法
implicitly[Fuge#A =:= String]
  • instanceからアクセスする場合
val fuge = new Fuge{}
implicitly[fuge.A =:= String]
Why not register and get more from Qiita?
