def ensuringValid(value: Float): PosZFiniteFloat

A factory/assertion method that produces a PosZFiniteFloat given a valid Float value, or throws AssertionError, if given an invalid Float value.

A factory/assertion method that produces a PosZFiniteFloat given a valid Float value, or throws AssertionError, if given an invalid Float 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 Float value and if it is a finite non-negative Float, it will return a PosZFiniteFloat representing that value. Otherwise, the passed Float value is not finite 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 Float literals at compile time, whereas from inspects Float 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 Float is positive.

Value parameters

Attributes

Returns

the specified Float value wrapped in a PosZFiniteFloat, if it is finite non-negative, else throws AssertionError.

Throws

A factory method that produces an Option[PosZFiniteFloat] given a Float value.

This method will inspect the passed Float value and if it is a finite non-negative Float, it will return a PosZFiniteFloat representing that value wrapped in a Some. Otherwise, the passed Float value is not finite non-negative, so this method will return None.

A validation method that produces a Pass given a valid Float 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 Float value and if it is a finite non-negative Float, it will return a Pass.

A factory/validation method that produces a PosZFiniteFloat, 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 finite non-negative Int, it will return a PosZFiniteFloat representing that value, wrapped in a Right.

implicit inline def apply(value: => Float): PosZFiniteFloat

A factory method, implemented via a macro, that produces a PosZFiniteFloat if passed a valid Float literal, otherwise a compile time error.

A factory method, implemented via a macro, that produces a PosZFiniteFloat if passed a valid Float literal, otherwise a compile time error.

The macro that implements this method will inspect the specified Float expression at compile time. If the expression is a finite non-negative Float literal, it will return a PosZFiniteFloat representing that value. Otherwise, the passed Float expression is either a literal that is not finite non-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 Float literals at compile time, whereas from inspects Float values at run time.

Value parameters

value

the Float literal expression to inspect at compile time, and if finite non-negative, to return wrapped in a PosZFiniteFloat at run time.

Attributes

Returns

the specified, valid Float literal value wrapped in a PosZFiniteFloat. (If the specified expression is not a valid Float literal, the invocation of this method will not compile.)
