  8. implicit def apply(value: Int): PosZInt

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

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

    The macro that implements this method will inspect the specified Int expression at compile time. If the expression is a positive Int literal, i.e., with a value greater than 0, it will return a PosZInt representing that value. Otherwise, the passed Int expression is either a literal that is 0 or 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 Int literals at compile time, whereas from inspects Int values at run time.

    value

    the Int literal expression to inspect at compile time, and if positive, to return wrapped in a PosZInt at run time.

    returns

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

  11. def ensuringValid(value: Int): PosZInt

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

    A factory/assertion method that produces a PosZInt given a valid Int value, or throws AssertionError, if given an invalid Int 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 Int value and if it is a non-negative Int, it will return a PosZInt representing that value. Otherwise, the passed Int 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 Int literals at compile time, whereas this method inspects Int 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 an Int is non-negative.

    value

    the Int to inspect, and if non-negative, return wrapped in a PosZInt.

    returns

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

    Exceptions thrown
    AssertionError

    if the passed value is not non-negative

  15. def from(value: Int): Option[PosZInt]

    A factory method that produces an Option[PosZInt] given an Int value.

    A factory method that produces an Option[PosZInt] given an Int value.

    This method will inspect the passed Int value and if it is a non-negative Int, i.e., a non-negative integer value, it will return a PosZInt representing that value, wrapped in a Some. Otherwise, the passed Int value is not non-negative integer value, 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 Int literals at compile time, whereas from inspects Int values at run time.

    value

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

    returns

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

  16. def fromOrElse(value: Int, default: ⇒ PosZInt): PosZInt

    A factory method that produces a PosZInt given a Int value and a default PosZInt.

    A factory method that produces a PosZInt given a Int value and a default PosZInt.

    This method will inspect the passed Int value and if it is a positive Int, i.e., a value greater than 0.0, it will return a PosZInt representing that value. Otherwise, the passed Int value is 0 or 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 Int literals at compile time, whereas from inspects Int values at run time.

    value

    the Int to inspect, and if positive, return.

    default

    the PosZInt to return if the passed Int value is not positive.

    returns

    the specified Int value wrapped in a PosZInt, if it is positive, else the default PosZInt value.

  18. def goodOrElse[B](value: Int)(f: (Int) ⇒ B): Or[PosZInt, B]

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

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

    This method will inspect the passed Int value and if it is a non-negative Int, it will return a PosZInt representing that value, wrapped in a Good. Otherwise, the passed Int value is not non-negative, so this method will return a result of type B obtained by passing the invalid Int 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 Int literals at compile time, whereas this method inspects Int values at run time.

    value

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

    returns

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

    A validation method that produces a Pass given a valid Int 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 Int value and if it is a non-negative Int, it will return a Pass. Otherwise, the passed Int value is non-negative, so this method will return a result of type E obtained by passing the invalid Int value to the given function f, wrapped in a Fail.

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.
