v1.4.0 Changes
January 21, 2021
➕ Added
- 👌 Support for wrapping constructors and fallbacks, see release notes for dry-types 1.5.0 (@flash-gordon)
- 👌 Improvements of the attribute DSL, now it's possible to use optional structs as a base class (@flash-gordon) ```ruby class User < Dry::Struct attribute :name, Types::String attribute :address, Dry::Struct.optional do attribute :city, Types::String end end
User.new(name: "John", address: nil) # => #
```
[Compare v1.3.0...v1.4.0](https://github.com/dry-rb/dry-struct/compare/v1.3.0...v1.4.0)
```

v1.3.0 Changes

February 10, 2020

➕ Added

Nested structures will reuse type and key transformations from the enclosing struct (@flash-gordon)

  class User < Dry::Struct
    transform_keys(&:to_sym)

    attribute :name, Types::String
    attribute :address do
      # this struct will inherit transform_keys(&:to_sym)
      attribute :city, Types::String
    end

    # nested struct will _not_ transform keys because a parent
    # struct is given
    attribute :contacts, Dry::Struct do
      attribute :email, Types::String
    end
  end

Dry::Struct::Constructor finally acts like a fully-featured type (@flash-gordon)
0️⃣ Dry::Struct.abstract declares a struct class as abstract. An abstract class is used as a default superclass for nested structs (@flash-gordon)
Dry::Struct.to_ast and struct compiler (@flash-gordon)
Struct composition with Dry::Struct.attributes_from. It's more flexible than inheritance (@waiting-for-dev + @flash-gordon)

  class Address < Dry::Struct
    attribute :city, Types::String
    attribute :zipcode, Types::String
  end

  class Buyer < Dry::Struct
    attribute :name, Types::String
    attributes_from Address
  end

  class Seller < Dry::Struct
    attribute :name, Types::String
    attribute :email, Types::String
    attributes_from Address
  end

🔄 Changed

📇 [internal] metadata is now stored inside schema (@flash-gordon)

Compare v1.2.0...v1.3.0

v1.2.0 Changes
December 20, 2019
1.2.0 2019-12-20

🔄 Changed
- Dry::Struct::Value is deprecated. Dry::Struct instances were never meant to be mutable, we have no support for this. The only difference between Dry::Struct and Dry::Struct::Value is that the latter is deeply frozen. Freezing objects slows the code down and gives you very little benefit in return. If you have a use case for Value, it won't be hard to roll your own solution using ice_nine (flash-gordon)
- In the thread of the previous change, structs now use immutable equalizer. This means Struct#hash memoizes its value after the first invocation. Depending on the case, this may speed up your code significantly (flash-gordon)
Compare v1.1.1...v1.2.0

v1.1.1 Changes

October 13, 2019

🔄 Changed

Pattern matching syntax is simplified with deconstruct_keys (k-tsj)

  User = Dry.Struct(name: 'string', email: 'string')

  user = User.new(name: 'John Doe', email: '[email protected]')

  case user
  in User(name: 'John Doe', email:)
    puts email
  else
    puts 'Not John'
  end

See more examples in the specs.

v1.1.0 Changes

October 07, 2019

1.1.0 2019-10-07

➕ Added

🍱 Experimental support for pattern matching 🎉 (flash-gordon)

User = Dry.Struct(name: 'string', email: 'string') user = User.new(name: 'John Doe', email: '[email protected]')case userin User({ name: 'John Doe', email: }) puts emailelseputs 'Not John'end

See more examples in the specs.

Compare v1.0.0...v1.1.0

v1.0.0 Changes
April 23, 2019
➕ Added
- Struct.call now accepts an optional block that will be called on failed coercion. This behavior is consistent with dry-types 1.0. Note that .new doesn't take a block (flash-gordon) ruby User = Dry::Struct(name: 'string') User.(1) { :oh_no } # => :oh_no
🔄 Changed
- valid? and === behave differently, === works the same way Class#=== does and valid? checks if the value can be coerced to the struct (flash-gordon)
Compare v0.7.0...v1.0.0
v0.7.0 Changes
March 22, 2019
🔄 Changed
- [BREAKING] Struct.input was renamed Struct.schema, hence Struct.schema returns an instance of Dry::Types::Hash::Schema rather than a Hash. Schemas are also implementing Enumerable but they iterate over key types. New API: ruby User.schema.each do |key| puts "Key name: #{ key.name }" puts "Key type: #{ key.type }" end To get a type by its name use .key: ruby User.schema.key(:id) # => #<Dry::Types::Hash::Key ...>
- [BREAKING] transform_types now passes one argument to the block, an instance of the Key type. Combined with the new API from dry-types it simplifies declaring omittable keys: ruby class StructWithOptionalKeys < Dry::Struct transform_types { |key| key.required(false) } # or simply transform_types(&:omittable) end
- ⚡️ Dry::Stuct#new is now more efficient for partial updates (flash-gordon)
- ✅ Ruby 2.3 is EOL and not officially supported. It may work but we don't test it.
Compare v0.6.0...v0.7.0
v0.6.0 Changes
March 22, 2019
➕ Added
- Struct.attribute? is an easy way to define omittable attributes (flash-gordon):
```
  class User < Dry::Struct
    attribute  :name,  Types::Strict::String
    attribute? :email, Types::Strict::String
  end
  # User.new(name: 'John') # => #<User name="John">
```
🛠 Fixed
- Struct#to_h recursively converts hash values to hashes, this was done to be consistent with current behavior for arrays (oeoeaio + ZimbiX)
🔄 Changed
- 🗄 [BREAKING] Struct.attribute? in the old sense is deprecated, use has_attribute? as a replacement
Compare v0.5.1...v0.6.0
v0.5.1 Changes
August 11, 2018
➕ Added
- 🖨 Pretty print extension (ojab) ruby Dry::Struct.load_extensions(:pretty_print) PP.pp(user) #<Test::User name="Jane", age=21, address=#<Test::Address city="NYC", zipcode="123">>
🛠 Fixed
- Constant resolution is now restricted to the current module when structs are automatically defined using the block syntax. This shouldn't break any existing code (piktur)
Compare v0.5.0...v0.5.1
v0.5.0 Changes
May 03, 2018
💥 BREAKING CHANGES
- 🚚 constructor_type was removed, use transform_types and transform_keys as a replacement (see below)
- Default types are evaluated only on missing values. Again, use tranform_types as a work around for nils
- 👍 Values are now stored within a single instance variable names @attributes, this sped up struct creation and improved support for reserved attribute names such as hash, they don't get a getter but still can be read via #[]
- 💎 Ruby 2.3 is a minimal supported version
➕ Added
- ⏪ Dry::Struct.transform_types accepts a block which is yielded on every type to add. Since types are dry-types' objects that come with a robust DSL it's rather simple to restore the behavior of constructor_type. See https://github.com/dry-rb/dry-struct/pull/64 for details (flash-gordon)
Example: evaluate defaults on nil values
```
  class User < Dry::Struct
    transform_types do |type|
      type.constructor { |value| value.nil? ? Undefined : value  }
    end
  end
```
- Data::Struct.transform_keys accepts a block/proc that transforms keys of input hashes. The most obvious usage is simbolization but arbitrary transformations are allowed (flash-gordon)
- 🏗 Dry.Struct builds a struct by a hash of attribute names and types (citizen428)
```
  User = Dry::Struct(name: 'strict.string') do
    attribute :email, 'strict.string'
  end
```
- 🆕 Support for Struct.meta, note that .meta returns a new class (flash-gordon)
```
  class User < Dry::Struct
    attribute :name, Dry::Types['strict.string']
  end

  UserWithMeta = User.meta(foo: :bar)

  User.new(name: 'Jade').class == UserWithMeta.new(name: 'Jade').class # => false
```
- 👍 Struct.attribute yields a block with definition for nested structs. It defines a nested constant for the new struct and supports arrays (AMHOL + flash-gordon)
```
    class User < Dry::Struct
      attribute :name, Types::Strict::String
      attribute :address do
        attribute :country, Types::Strict::String
        attribute :city, Types::Strict::String
      end
      attribute :accounts, Types::Strict::Array do
        attribute :currency, Types::Strict::String
        attribute :balance, Types::Strict::Decimal
      end
    end

    # ^This automatically defines User::Address and User::Account
```
🛠 Fixed
- ➕ Adding a new attribute invalidates attribute_names (flash-gordon)
- Struct classes track subclasses and define attributes in them, now it doesn't matter whether you define attributes first and then subclass or vice versa. Note this can lead to memory leaks in Rails environment when struct classes are reloaded (flash-gordon)
