Int
, which isPosInt(1)
. - implicit macro def apply(value: Int): PosInt
A factory method, implemented via a macro, that produces a
PosInt
if passed a validInt
literal, otherwise a compile time error.A factory method, implemented via a macro, that produces a
PosInt
if passed a validInt
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 positiveInt
literal, i.e., with a value greater than 0, it will return aPosInt
representing that value. Otherwise, the passedInt
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 inspectsInt
literals at compile time, whereasfrom
inspectsInt
values at run time.- value
the
Int
literal expression to inspect at compile time, and if positive, to return wrapped in aPosInt
at run time.- returns
the specified, valid
Int
literal value wrapped in aPosInt
. (If the specified expression is not a validInt
literal, the invocation of this method will not compile.)

value.A factory method that produces an
Option[PosInt]
given anInt
value.This method will inspect the passed
Int
value and if it is a positiveInt
, i.e., a value greater than 0, it will return aPosInt
representing that value, wrapped in aSome
. Otherwise, the passedInt
value is 0 or negative, so this method will returnNone
.This factory method differs from the
apply

is implemented via a macro that inspectsInt
literals at compile time, whereasfrom

the
Int
to inspect, and if positive, return wrapped in aSome[PosInt]
.- returns
the specified
Int
value wrapped in aSome[PosInt]
