final val MaxValue: NumericChar
The largest value representable as a NumericChar.
final val MinValue: NumericChar
The smallest value representable as a NumericChar.
implicit macro def apply(value: Char): NumericChar
A factory method, implemented via a macro, that produces a NumericChar if passed a valid Char literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a NumericChar if passed a valid Char literal, otherwise a compile time error.
The macro that implements this method will inspect the specified Char expression at compile time. If the expression is a numeric Char literal, i.e., a value between '0' and '9', it will return a NumericChar representing that value. Otherwise, the passed Char expression is either a literal that is not numeric, 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 Char literals at compile time, whereas from inspects Char values at run time.
value
the Char literal expression to inspect at compile time, and if numeric, to return wrapped in a NumericChar at run time.
returns
the specified, valid Char literal value wrapped in a NumericChar. (If the specified expression is not a valid Char literal, the invocation of this method will not compile.)

def ensuringValid(value: Char): NumericChar
A factory/assertion method that produces a NumericChar given a valid Char value, or throws AssertionError, if given an invalid Char value.
A factory/assertion method that produces a NumericChar given a valid Char value, or throws AssertionError, if given an invalid Char 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 Char value and if it is a numeric Char, it will return a NumericChar representing that value. Otherwise, the passed Char value is not numeric, 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 Char literals at compile time, whereas this method inspects Char 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 Char is numeric.
value
the Char to inspect, and if numeric, return wrapped in a NumericChar.
returns
the specified Char value wrapped in a NumericChar, if it is numeric, else throws AssertionError.
Exceptions thrown
AssertionError if the passed value is not numeric

def from(value: Char): Option[NumericChar]
A factory method that produces an Option[NumericChar] given a Char value.
A factory method that produces an Option[NumericChar] given a Char value.
This method will inspect the passed Char value and if it is a numeric Char, i.e., between '0' and '9', it will return a NumericChar representing that value, wrapped in a Some. Otherwise, the passed Char value is not a numeric character 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 Char literals at compile time, whereas from inspects Char values at run time.
value
the Char to inspect, and if numeric, return wrapped in a Some[NumericChar].
returns
the specified Char value wrapped in a Some[NumericChar], if it is numeric, else None.
def fromOrElse(value: Char, default: => NumericChar): NumericChar
A factory method that produces a NumericChar given a Char value and a default NumericChar.
A factory method that produces a NumericChar given a Char value and a default NumericChar.
This method will inspect the passed Char value and if it is a valid numeric Char (between '0' and '9'), it will return a NumericChar representing that value. Otherwise, the passed Char value is a non-digit character, 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 Char literals at compile time, whereas fromOrElse inspects Char values at run time.
value
the Char to inspect, and if numeric, return.
default
the NumericChar to return if the passed Char value is not numeric.
returns
the specified Char value wrapped in a NumericChar, if it is numeric, else the default NumericChar value.

def goodOrElse[B](value: Char)(f: (Char) => B): Or[NumericChar, B]
A factory/validation method that produces a NumericChar, wrapped in a Good, given a valid Char value, or if the given Char is invalid, an error value of type B produced by passing the given invalid Char value to the given function f, wrapped in a Bad.
A factory/validation method that produces a NumericChar, wrapped in a Good, given a valid Char value, or if the given Char is invalid, an error value of type B produced by passing the given invalid Char value to the given function f, wrapped in a Bad.
This method will inspect the passed Char value and if it is a numeric Char, it will return a NumericChar representing that value, wrapped in a Good. Otherwise, the passed Char value is NOT numeric, so this method will return a result of type B obtained by passing the invalid Char 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 Char literals at compile time, whereas this method inspects Char values at run time.
value
the Char to inspect, and if numeric, return wrapped in a Good(NumericChar).
returns
the specified Char value wrapped in a Good(NumericChar), if it is numeric, else a Bad(f(value)).

def passOrElse[E](value: Char)(f: (Char) => E): Validation[E]
A validation method that produces a Pass given a valid Char value, or an error value of type E produced by passing the given invalid Char value to the given function f, wrapped in a Fail.
A validation method that produces a Pass given a valid Char value, or an error value of type E produced by passing the given invalid Char value to the given function f, wrapped in a Fail.
This method will inspect the passed Char value and if it is a numeric Char (between '0' and '9'), it will return a Pass. Otherwise, the passed Char value is non-numeric, so this method will return a result of type E obtained by passing the invalid Char 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 Char literals at compile time, whereas this method inspects Char values at run time.
value
the Char to validate that it is numeric.
returns
a Pass if the specified Char value is numeric, else a Fail containing an error value produced by passing the specified Char to the given function f.
def rightOrElse[L](value: Char)(f: (Char) => L): Either[L, NumericChar]
A factory/validation method that produces a NumericChar, wrapped in a Right, given a valid Char value, or if the given Char is invalid, an error value of type L produced by passing the given invalid Char value to the given function f, wrapped in a Left.
A factory/validation method that produces a NumericChar, wrapped in a Right, given a valid Char value, or if the given Char is invalid, an error value of type L produced by passing the given invalid Char value to the given function f, wrapped in a Left.
This method will inspect the passed Char value and if it is a numeric Char (between '0' and '9'), it will return a NumericChar representing that value, wrapped in a Right. Otherwise, the passed Char value is NOT numeric, so this method will return a result of type L obtained by passing the invalid Char value to the given function f, wrapped in a Left.

value

returns
the specified Char value wrapped in a Right(NumericChar), if it is numeric, else a Left(f(value)).
