-   implicit macro  def apply(value: Int): NegIntA factory method, implemented via a macro, that produces a NegIntif passed a validIntliteral, otherwise a compile time error.A factory method, implemented via a macro, that produces a NegIntif passed a validIntliteral, otherwise a compile time error.The macro that implements this method will inspect the specified Intexpression at compile time. If the expression is a positiveIntliteral, i.e., with a value greater than 0, it will return aNegIntrepresenting that value. Otherwise, the passedIntexpression 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 fromfactory method in that this method is implemented via a macro that inspectsIntliterals at compile time, whereasfrominspectsIntvalues at run time.- value
- the - Intliteral expression to inspect at compile time, and if positive, to return wrapped in a- NegIntat run time.
- returns
- the specified, valid - Intliteral value wrapped in a- NegInt. (If the specified expression is not a valid- Intliteral, the invocation of this method will not compile.)

-    def ensuringValid(value: Int): NegIntA factory/assertion method that produces a NegIntgiven a validIntvalue, or throwsAssertionError, if given an invalidIntvalue.A factory/assertion method that produces a NegIntgiven a validIntvalue, or throwsAssertionError, if given an invalidIntvalue.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 ensuringValidcall will always succeed, you should use one of the other factory or validation methods provided on this object instead:isValid,tryingValid,passOrElse,goodOrElse, orrightOrElse.This method will inspect the passed Intvalue and if it is a negativeInt, it will return aNegIntrepresenting that value. Otherwise, the passedIntvalue is not negative, so this method will throwAssertionError.This factory method differs from the applyfactory method in thatapplyis implemented via a macro that inspectsIntliterals at compile time, whereas this method inspectsIntvalues at run time. It differs from a vanillaassertorensuringcall in that you get something you didn't already have if the assertion succeeds: a type that promises anIntis negative.- value

- returns
- the specified - Intvalue wrapped in a- NegInt, if it is negative, else throws- AssertionError.

-    def from(value: Int): Option[NegInt]A factory method that produces an Option[NegInt]given anIntvalue.A factory method that produces an Option[NegInt]given anIntvalue.This method will inspect the passed Intvalue and if it is a negativeInt, i.e., a negative integer value, it will return aNegIntrepresenting that value, wrapped in aSome. Otherwise, the passedIntvalue is not negative integer value, so this method will returnNone.This factory method differs from the applyfactory method in thatapplyis implemented via a macro that inspectsIntliterals at compile time, whereasfrominspectsIntvalues at run time.- value

-    def fromOrElse(value: Int, default: => NegInt): NegIntA factory method that produces a NegIntgiven aIntvalue and a defaultNegInt.A factory method that produces a NegIntgiven aIntvalue and a defaultNegInt.This method will inspect the passed Intvalue and if it is a positiveInt, i.e., a value greater than 0.0, it will return aNegIntrepresenting that value. Otherwise, the passedIntvalue is 0 or negative, so this method will return the passeddefaultvalue.This factory method differs from the applyfactory method in thatapplyis implemented via a macro that inspectsIntliterals at compile time, whereasfrominspectsIntvalues at run time.- value
