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.
the Int literal expression to inspect at compile time,
and if positive, to return wrapped in a PosZInt at run time.
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.)
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.
the Int to inspect, and if non-negative, return
wrapped in a PosZInt.
the specified Int value wrapped
in a PosZInt, if it is non-negative, else throws AssertionError.

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

in a Some[PosZInt], if it is non-negative, else None.
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 value is not positive.
the specified Int value wrapped in a
PosZInt, if it is positive, else the
default PosZInt value.
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.

A predicate method that returns true if a given
Int value is non-negative.
A predicate method that returns true if a given

given invalid Int value
to the given function f, wrapped in a Fail.
A validation method that produces a Pass
given a valid Int value, or

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.
