Module: Strava::DeepCopyable

Included in:
Api::Pagination, Web::Response
Defined in:
lib/strava/deep_copyable.rb

Overview

Mixin module for deep copying objects.

This module provides a helper method for creating deep copies of objects using Ruby's Marshal serialization. Unlike shallow cloning (which only duplicates the top-level object), deep copying recursively duplicates all nested objects and collections.

This is particularly useful when working with model objects that contain nested hashes or arrays, ensuring modifications to the copy don't affect the original object.

Examples:

Deep copying a nested hash

include Strava::DeepCopyable
original = {a: {b: [1, 2, 3]}}
copy = deep_copy(original)
copy[:a][:b] << 4
original[:a][:b]  # => [1, 2, 3] (unchanged)
