Super basic type checking functions in ruby.
module Type
include Kinda.module
end
Type[Float].call(1.0)
# => 1.0
Type[Float].call(1)
# => Kinda::ConstraintError: expected Float but given Fixnum
In addition to any normal Ruby class the following custom types are available.
Type[Bool].call(true)
# => true
Type[Bool].call(false)
# => false
Type[Bool].call(nil)
# => Kinda::ConstraintError: expected [TrueClass, FalseClass] but given NilClass
New types can also be defined in terms of existing types.
require 'bigdecimal'
Decimal = [BigDecimal, Float]
Type[Decimal].call(BigDecimal.new('1.0'))
# => #<BigDecimal:7fdd2c3aa9b0,'0.1E1',9(18)>
MaybeDecimal = [Nil, Decimal]
Type[MaybeDecimal].call(1.0)
# => 1.0
Type[MaybeDecimal].call(nil)
# => nil
Type[MaybeDecimal].call(1)
# => Kinda::ConstraintError: expected [NilClass, BigDecimal, Float] but given Fixnum
