Instance Method Details

#generate(name, &block) ⇒ Type::Definition #generate(name) ⇒ Type::Definition::Proxy

Returns @example ~~~ ruby

Type::scalar(:Int32).from(:Integer) do
  int32_range = (-1 << 31) ... (1 << 31)
  validate do |input|
    int32_range.include?(input)
  end
end

~~~.

Overloads:

• #generate(name, &block) ⇒ Type::Definition

  The block is called in the context of the definition, and is expected to call one of ‘#validate` or `#cast` with appropriate blocks. ~~~ ruby

  Type::scalar(:Integer) do
    validate do |input|
      input.kind_of?(::Integer)
    end
    cast do |input|
      Kernel::Integer(input)
    end
  end
  

  ~~~

  Parameters:

  • name (Symbol, nil) —

    (nil) Capital-letter symbol (e.g., ‘:Int32`) for which to register this definition globally.

  Returns:

  • (Type::Definition)
• #generate(name) ⇒ Type::Definition::Proxy

  Returns You are expected to call from(type_def, &block) to finish the definition.

  Parameters:

  • name (Symbol, nil) —

    (nil) Capital-letter symbol (e.g., ‘:Int32`) for which to register this definition globally.

  Returns:

  • (Type::Definition::Proxy) —

    You are expected to call from(type_def, &block) to finish the definition

Returns:

• (Type::Definition, Type::Definition::Proxy) —

  @example ~~~ ruby

  Type::scalar(:Int32).from(:Integer) do
    int32_range = (-1 << 31) ... (1 << 31)
    validate do |input|
      int32_range.include?(input)
    end
  end
