Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

A minimal hash implementation that allows values to be looked up with either string or symbol keys.

The keys stored in the hash are left exactly as they are; only lookups are indifferent. Log entry attributes are matched with string keys, but matchers that do their own key lookups on the attributes hash (i.e. RSpec's hash_including) have no way of knowing that. Wrapping the attributes in this class lets those matchers use either form.

Class Method Details

.wrap(value) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Recursively wrap a value so that any hashes in it, including hashes nested inside arrays, allow indifferent key lookups. Values that are not hashes or arrays are returned as is.

Parameters:

  • value (Object) —

    The value to wrap.

Returns:

  • (Object) —

    The wrapped value.
