将哈希转换为结构 [英] Convert a hash into a struct

问题描述

如何在 ruby​​ 中将散列转换为结构体?

How can I convert a hash into a struct in ruby?

鉴于此:

h = { :a => 1, :b => 2 }

我想要一个结构体:

s.a == 1
s.b == 2

推荐答案

如果不是特别必须是 Struct 而可以是 开放结构:

If it doesn't specifically have to be a Struct and instead can be an OpenStruct:

pry(main)> require 'ostruct'
pry(main)> s = OpenStruct.new(h)
=> #<OpenStruct a=1, b=2>
pry(main)> puts s.a, s.b
1
2
