#deep_merge(other_hash) ⇒ Hash

Returns a new hash containing the contents of other_hash and the

contents of self. If the value for entries with duplicate keys
is a Hash, it will be merged recursively, otherwise it will be that
of other_hash.

Examples:

Merging two hashes

h1 = {:a => 3, {:b => 3, :c => 7}}
h2 = {:a => 22, c => 4, {:b => 5}}

h1.deep_merge(h2) #=> {:a => 22, c => 4, {:b => 5, :c => 7}}

Parameters:

Returns:

  • (Hash) —

    Containing the merged values
