  8. implicit macro def apply(value: Float): PosZFloat

    A factory method, implemented via a macro, that produces a PosZFloat if passed a valid Float literal, otherwise a compile time error.

    A factory method, implemented via a macro, that produces a PosZFloat if passed a valid Float literal, otherwise a compile time error.

    The macro that implements this method will inspect the specified Float expression at compile time. If the expression is a non-negative Float literal, it will return a PosZFloat representing that value. Otherwise, the passed Float expression is either a literal that is not non-negative, or is not a literal, so this method will give a compiler error.

    This factory method differs from the from factory method in that this method is implemented via a macro that inspects Float literals at compile time, whereas from inspects Float values at run time.

    value

    the Float literal expression to inspect at compile time, and if non-negative, to return wrapped in a PosZFloat at run time.

    returns

    the specified, valid Float literal value wrapped in a PosZFloat. (If the specified expression is not a valid Float literal, the invocation of this method will not compile.)

  11. def ensuringValid(value: Float): PosZFloat

    A factory/assertion method that produces a PosZFloat given a valid Float value, or throws AssertionError, if given an invalid Float value.

    A factory/assertion method that produces a PosZFloat given a valid Float value, or throws AssertionError, if given an invalid Float value.

    Note: you should use this method only when you are convinced that it will always succeed, i.e., never throw an exception. It is good practice to add a comment near the invocation of this method indicating why you think it will always succeed to document your reasoning. If you are not sure an ensuringValid call will always succeed, you should use one of the other factory or validation methods provided on this object instead: isValid, tryingValid, passOrElse, goodOrElse, or rightOrElse.

    This method will inspect the passed Float value and if it is a non-negative Float, it will return a PosZFloat representing that value. Otherwise, the passed Float value is not non-negative, so this method will throw AssertionError.

    This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas from inspects Float values at run time. It differs from a vanilla assert or ensuring call in that you get something you didn't already have if the assertion succeeds: a type that promises a Float is positive.

    value

    the Float to inspect, and if non-negative, return wrapped in a PosZFloat.

    returns

    the specified Float value wrapped in a PosZFloat, if it is non-negative, else throws AssertionError.

    Exceptions thrown

    AssertionError if the passed value is not non-negative

  15. def from(value: Float): Option[PosZFloat]

    A factory method that produces an Option[PosZFloat] given a Float value.

    A factory method that produces an Option[PosZFloat] given a Float value.

    This method will inspect the passed Float value and if it is a non-negative Float, it will return a PosZFloat representing that value wrapped in a Some. Otherwise, the passed Float value is not non-negative, so this method will return None.

    This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas from inspects Float values at run time.

    value

    the Float to inspect, and if non-negative, return wrapped in a Some[PosZFloat].

    returns

    the specified Float value wrapped in a Some[PosZFloat], if it is non-negative, else None.

  16. def fromOrElse(value: Float, default: => PosZFloat): PosZFloat

    A factory method that produces a PosZFloat given a Float value and a default PosZFloat.

    A factory method that produces a PosZFloat given a Float value and a default PosZFloat.

    This method will inspect the passed Float value and if it is a non-negative Float, it will return a PosZFloat representing that value. Otherwise, the passed Float value is not non-negative, so this method will return the passed default value.

    This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas from inspects Float values at run time.

    value

    the Float to inspect, and if non-negative, return.

    default

    the PosZFloat to return if the passed Float value is not non-negative.

    returns

    the specified Float value wrapped in a PosZFloat, if it is non-negative, else the default PosZFloat value.

    A factory/validation method that produces a PosZFloat, wrapped in a Good, given a valid Float value, or if the given Float is invalid, an error value of type B produced by passing the given invalid Float value to the given function f, wrapped in a Bad.

    This method will inspect the passed Float value and if it is a non-negative Float, it will return a PosZFloat representing that value, wrapped in a Good. Otherwise, the passed Float value is not non-negative, so this method will return a result of type B obtained by passing the invalid Float value to the given function f, wrapped in a Bad.

    This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas this method inspects Float values at run time.

    value

    the Float to inspect, and if non-negative, return wrapped in a Good(PosZFloat).

    returns

    the specified Float value wrapped in a Good(PosZFloat), if it is non-negative, else a Bad(f(value)).

    A validation method that produces a Pass given a valid Float value, or an error value of type E produced by passing the given invalid Int value to the given function f, wrapped in a Fail.

    This method will inspect the passed Float value and if it is a non-negative Float, it will return a Pass. Otherwise, the passed Float value is non-negative, so this method will return a result of type E obtained by passing the invalid Float value to the given function f, wrapped in a Fail.

    This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Float literals at compile time, whereas this method inspects Float values at run time.

    returns

    a Pass if the specified Float value is non-negative, else a Fail containing an error value produced by passing the specified Float to the given function f.

  27. def rightOrElse[L](value: Float)(f: (Float) => L): Either[L, PosZFloat]

    This method will inspect the passed Int value and if it is a non-negative Int, it will return a PosZFloat representing that value, wrapped in a Right. Otherwise, the passed Int value is not non-negative, so this method will return a result of type L obtained by passing the invalid Int value to the given function f, wrapped in a Left.

    This factory method differs from the apply factory method in that apply is implemented via a macro that inspects Int literals at compile time, whereas this method inspects Int values at run time.
