object Eventually extends Eventually
Companion object that facilitates the importing of Eventually
members as
an alternative to mixing in the trait. One use case is to import Eventually
's members so you can use
them in the Scala interpreter:

.The
Span
is scaled by invoking itsscaledBy
method, thus this method has the same behavior: The value returned byspanScaleFactor
can be any positive number or zero, including a fractional number. A number greater than one will scale theSpan
up to a larger value. A fractional number will scale it down to a smaller value. A factor of 1.0 will cause the exact sameSpan
to be returned. A factor of zero will causeSpan.ZeroLength
to be returned. If overflow occurs,Span.Max

will be returned.- Definition Classes
