class Prism::HashNode
表示一个哈希字面量。
{ a => b }
^^^^^^^^^^
属性
哈希的元素。这些可以是 AssocNode 或 AssocSplatNode。
{ a: b }
^^^^
{ **foo }
^^^^^

# File lib/prism/node.rb, line 8386 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
实现节点的相等性判断。这实际上是 ==,但不比较 location 的值。仅检查 location 是否存在。
