Class: Dry::Struct::Value

Inherits:

Dry::Struct

• Object
• Dry::Struct
• Dry::Struct::Value

Defined in:

lib/dry/struct/value.rb

Overview

Value objects behave like Dry::Structs but deeply frozen using ice_nine

Examples:

class Location < Dry::Struct::Value
  attribute :lat, Types::Strict::Float
  attribute :lng, Types::Strict::Float
end

loc1 = Location.new(lat: 1.23, lng: 4.56)
loc2 = Location.new(lat: 1.23, lng: 4.56)

loc1.frozen? #=> true
loc2.frozen? #=> true
loc1 == loc2 #=> true
