How to use Struct In Ruby

Struct is a built-in Ruby class that allows you to create a new class with specified attributes.

Syntax:

ClassName = Struct.new(:attribute1, :attribute2, …)

object = ClassName.new(hash[:key1], hash[:key2], …)

Example:

In this example we define a Struct class Person with attributes name, age, and city. Then, we create a new object person from the hash containing person information, passing each value as an argument.

Ruby

# Define a Struct class with attributes
Person = Struct.new(:name, :age, :city)

# Hash containing person information
person_hash = { name: 'John', age: 30, city: 'New York' }

# Convert hash to object using Struct
person = Person.new(*person_hash.values)

# Accessing attributes of the object
puts "Name: #{person.name}"   
puts "Age: #{person.age}"    
puts "City: #{person.city}"

Output

Name: John
Age: 30
City: New York
