Instance methods

Source
to_json(builder : 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_s(io : IO) : Nil

Appends a String representation of this enum member to the given io.

See also: to_s.

Source
to_s

Returns a String representation of this enum member. In the case of regular enums, this is just the name of the member. In the case of flag enums, it's the names joined by vertical bars, or "None", if the value is zero.

If an enum's value doesn't match a member's value, the raw value is returned as a string.

Color::Red.to_s                     # => "Red"
IOMode::None.to_s                   # => "None"
(IOMode::Read | IOMode::Write).to_s # => "Read | Write"

Color.new(10).to_s # => "10"
