class Prism::HashNode
表示哈希字面量。
{ a => b } ^^^^^^^^^^
属性
哈希的元素。这些元素可以是 `AssocNode` 或 `AssocSplatNode`。
{ a: b } ^^^^ { **foo } ^^^^^

源码
# File lib/prism/node.rb, line 8283 def ===(other) other.is_a?(HashNode) && (opening_loc.nil? == other.opening_loc.nil?) && (elements.length == other.elements.length) && elements.zip(other.elements).all? { |left, right| left === right } && (closing_loc.nil? == other.closing_loc.nil?) end
实现节点的 case-equality。这实际上是 ==,但不比较位置的值。位置仅检查是否存在。
