Built-in Types

Built-in types are grouped under 6 categories:

  • definition - base type definitions with primitive class and options
  • strict - constrained types with a primitive type check applied to input
  • coercible - types with constructors using kernel coercions
  • params - types with constructors performing non-strict coercions specific to HTTP params
  • json - types with constructors performing non-strict coercions specific to JSON
  • maybe - types accepting either nil or a specific primitive type

Categories

Assuming you included types in a module called Types:

  • Base definitions:

    • Types::Any
    • Types::Nil
    • Types::Symbol
    • Types::Class
    • Types::True
    • Types::False
    • Types::Bool
    • Types::Integer
    • Types::Float
    • Types::Decimal
    • Types::String
    • Types::Date
    • Types::DateTime
    • Types::Time
    • Types::Array
    • Types::Hash

  • Strict types will raise an error if passed a value of the wrong type:

    • Types::Strict::Nil
    • Types::Strict::Symbol
    • Types::Strict::Class
    • Types::Strict::True
    • Types::Strict::False
    • Types::Strict::Bool
    • Types::Strict::Integer
    • Types::Strict::Float
    • Types::Strict::Decimal
    • Types::Strict::String
    • Types::Strict::Date
    • Types::Strict::DateTime
    • Types::Strict::Time
    • Types::Strict::Array
    • Types::Strict::Hash

  • Coercible types will attempt to cast values to the correct class using kernel coercion methods:

    • Types::Coercible::String
    • Types::Coercible::Integer
    • Types::Coercible::Float
    • Types::Coercible::Decimal
    • Types::Coercible::Array
    • Types::Coercible::Hash

  • Types suitable for Params param processing with coercions:

    • Types::Params::Nil
    • Types::Params::Date
    • Types::Params::DateTime
    • Types::Params::Time
    • Types::Params::True
    • Types::Params::False
    • Types::Params::Bool
    • Types::Params::Integer
    • Types::Params::Float
    • Types::Params::Decimal
    • Types::Params::Array
    • Types::Params::Hash

  • Types suitable for JSON processing with coercions:

    • Types::JSON::Nil
    • Types::JSON::Date
    • Types::JSON::DateTime
    • Types::JSON::Time
    • Types::JSON::Decimal
    • Types::JSON::Array
    • Types::JSON::Hash

  • Maybe strict types:

    • Types::Maybe::Strict::Class
    • Types::Maybe::Strict::String
    • Types::Maybe::Strict::Symbol
    • Types::Maybe::Strict::True
    • Types::Maybe::Strict::False
    • Types::Maybe::Strict::Integer
    • Types::Maybe::Strict::Float
    • Types::Maybe::Strict::Decimal
    • Types::Maybe::Strict::Date
    • Types::Maybe::Strict::DateTime
    • Types::Maybe::Strict::Time
    • Types::Maybe::Strict::Array
    • Types::Maybe::Strict::Hash

  • Maybe coercible types:

    • Types::Maybe::Coercible::String
    • Types::Maybe::Coercible::Integer
    • Types::Maybe::Coercible::Float
    • Types::Maybe::Coercible::Decimal
    • Types::Maybe::Coercible::Array
    • Types::Maybe::Coercible::Hash

Maybe types are not available by default - they must be loaded using Dry::Types.load_extensions(:maybe). See Optional Values for more information.
