Methods Symbol#as_json and Symbol.json_create may be used to serialize and deserialize a Symbol object; see Marshal.

Method Symbol#as_json serializes self, returning a 2-element hash representing self:

require 'json/add/symbol'
x = :foo.as_json
# => {"json_class"=>"Symbol", "s"=>"foo"}

Method JSON.create deserializes such a hash, returning a Symbol object:

Symbol.json_create(x) # => :foo

to_json (state = nil, *a)

Source

# File vendor/bundle/ruby/3.4.0/gems/json-2.10.2/lib/json/add/symbol.rb, line 39
def to_json(state = nil, *a)
  state = ::JSON::State.from_state(state)
  if state.strict?
    super
  else
    as_json.to_json(state, *a)
  end
end

Returns a JSON string representing self:

require 'json/add/symbol'
puts :foo.to_json

Output:

# {"json_class":"Symbol","s":"foo"}
