范围可以在 Scala 中匹配吗? [英] Can a range be matched in Scala?

问题描述

是否可以在 Scala 中匹配一系列值?

Is it possible to match a range of values in Scala?

例如:

val t = 5
val m = t match {
    0 until 10 => true
    _ => false
}

如果 t 介于 0 和 10 之间，则

m 将为 true，否则为 false.这一点当然是行不通的，但是有没有什么办法可以实现呢?

m would be true if t was between 0 and 10, but false otherwise. This little bit doesn't work of course, but is there any way to achieve something like it?

推荐答案

Guard using Range:

Guard using Range:

val m = t match {
  case x if 0 until 10 contains x => true
  case _ => false
}
