Source
to_json(json : JSON::Builder)

Serializes this enum member by name.

For non-flags enums, the serialization is a JSON string. The value is the member name (see #to_s) transformed with String#underscore.

enum Stages
  INITIAL
  SECOND_STAGE
end

Stages::INITIAL.to_json      # => %("initial")
Stages::SECOND_STAGE.to_json # => %("second_stage")

For flags enums, the serialization is a JSON array including every flagged member individually serialized in the same way as a member of a non-flags enum. None is serialized as an empty array, All as an array containing all members.

@[Flags]
enum Sides
  LEFT
  RIGHT
end

Sides::LEFT.to_json                  # => %(["left"])
(Sides::LEFT | Sides::RIGHT).to_json # => %(["left","right"])
Sides::All.to_json                   # => %(["left","right"])
Sides::None.to_json                  # => %([])

ValueConverter.to_json offers a different serialization strategy based on the member value.

Source
to_yaml(emitter : YAML::Nodes::Builder)

Serializes this enum member by name.

For non-flags enums, the serialization is a YAML string. The value is the member name (see #to_s) transformed with String#underscore.

enum Stages
  INITIAL
  SECOND_STAGE
end

Stages::INITIAL.to_yaml      # => %(--- initial\n)
Stages::SECOND_STAGE.to_yaml # => %(--- second_stage\n)

For flags enums, the serialization is a YAML sequence including every flagged member individually serialized in the same way as a member of a non-flags enum. None is serialized as an empty sequence, All as a sequence containing all members.

@[Flags]
enum Sides
  LEFT
  RIGHT
end

Sides::LEFT.to_yaml                  # => %(--- [left]\n)
(Sides::LEFT | Sides::RIGHT).to_yaml # => %(--- [left, right]\n)
Sides::All.to_yaml                   # => %(--- [left, right]\n)
Sides::None.to_yaml                  # => %(--- []\n)

ValueConverter.to_yaml offers a different serialization strategy based on the member value.
