Concrete methods
A factory/assertion method that produces an PosLong given a
valid Long value, or throws AssertionError,
if given an invalid Long value.
A factory/assertion method that produces an PosLong given a
valid Long value, or throws AssertionError,
if given an invalid Long 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 Long value and if
it is a positive Long, it will return a PosLong representing that value.
Otherwise, the passed Long value is not positive, 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 Long literals at
compile time, whereas from inspects
Long 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 Long is positive.
- Value parameters:
- value
the
Longto inspect, and if positive, return wrapped in aPosLong.
- Returns:
the specified
Longvalue wrapped in aPosLong, if it is positive, else throwsAssertionError.- Throws:
- AssertionError
if the passed value is not positive

A factory method that produces an Option[PosLong] given a
Long value.
A factory method that produces an Option[PosLong] given a
Long value.
This method will inspect the passed Long value and if
it is a positive Long, it will return a PosLong representing that value,
wrapped in a Some. Otherwise, the passed Long
value is not positive, 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 Long literals at
compile time, whereas from inspects
Long values at run time.

Long value and a default PosLong.
A factory method that produces a PosLong given a
Long value and a default PosLong.
This method will inspect the passed Long value and if
it is a positive Long, it will return a PosLong representing that value.
Otherwise, the passed Long value is not positive, 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 Long literals at
compile time, whereas from inspects
Long values at run time.
- Value parameters:

A factory/validation method that produces a PosLong, wrapped
in a Good, given a valid Long value, or if the
given Long is invalid, an error value of type B
produced by passing the given invalid Long value
to the given function f, wrapped in a Bad.
A factory/validation method that produces a PosLong, wrapped
in a Good, given a valid Long value, or if the
given Long is invalid, an error value of type B
produced by passing the given invalid Long value
to the given function f, wrapped in a Bad.
This method will inspect the passed Long value and if
it is a positive Long, it will return a PosLong
representing that value, wrapped in a Good.
Otherwise, the passed Long value is not positive, so this
method will return a result of type B obtained by passing
the invalid Long 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
Long literals at compile time, whereas this method inspects
Long values at run time.
- Value parameters:
- value
the
Longto inspect, and if positive, return wrapped in aGood(PosLong).
- Returns:
the specified
Longvalue wrapped in aGood(PosLong), if it is positive, else aBad(f(value)).- Source:

Long value is positive.
A predicate method that returns true if a given
Long value is positive.

A validation method that produces a Pass
given a valid Long 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.
A validation method that produces a Pass
given a valid Long 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 Long value and if
it is a positive Long, it will return a Pass.
Otherwise, the passed Long value is positive, so this
method will return a result of type E obtained by passing
the invalid Long 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
Long literals at compile time, whereas this method inspects

- Value parameters:
- value
the
Longto validate that it is positive.
- Returns:

A factory/validation method that produces a PosLong, wrapped
in a Right, given a valid Int value, or if the
given Int is invalid, an error value of type L
produced by passing the given invalid Int value
to the given function f, wrapped in a Left.
A factory/validation method that produces a PosLong, wrapped
in a Right, given a valid Int value, or if the
given Int is invalid, an error value of type L
produced by passing the given invalid Int value
to the given function f, wrapped in a Left.
This method will inspect the passed Int value and if
it is a positive Int, it will return a PosLong
representing that value, wrapped in a Right.
Otherwise, the passed Int value is not positive, 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.
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 parameters:

Intto inspect, and if positive, return wrapped in aRight(PosLong).
- Returns:
the specified
Intvalue wrapped in aRight(PosLong), if it is positive, else aLeft(f(value)).- Source:

A factory method, implemented via a macro, that produces a
PosLong if passed a valid Long
literal, otherwise a compile time error.
A factory method, implemented via a macro, that produces a
PosLong if passed a valid Long
literal, otherwise a compile time error.
The macro that implements this method will inspect the
specified Long expression at compile time. If
the expression is a positive Long literal,
it will return a PosLong representing that value.
Otherwise, the passed Long expression is either a literal
that is not positive, 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 Long literals at compile
time, whereas from inspects Long
values at run time.
- Value parameters:
- value
the
Longliteral expression to inspect at compile time, and if positive, to return wrapped in aPosLongat run time.
- Returns:
the specified, valid
Longliteral value wrapped in aPosLong. (If the specified expression is not a validLongliteral, the invocation of this method will not compile.)- Source:
