  6. def combine(x: FiniteDuration, y: FiniteDuration): FiniteDuration

    Associative operation which combines two values.

    Associative operation which combines two values.

    Example:

    scala> import cats.kernel.instances.string._
    scala> import cats.kernel.instances.int._
    scala> import cats.kernel.instances.option._
    
    scala> Semigroup[String].combine("Hello ", "World!")
    res0: String = Hello World!

  7. def combineAll(as: IterableOnce[FiniteDuration]): FiniteDuration

    Given a sequence of as, sum them using the monoid and return the total.

    Given a sequence of as, sum them using the monoid and return the total.

    Example:

    scala> import cats.kernel.instances.string._
    
    scala> Monoid[String].combineAll(List("One ", "Two ", "Three"))
    res0: String = One Two Three

  8. def combineAllOption(as: IterableOnce[FiniteDuration]): Option[FiniteDuration]

    Given a sequence of as, combine them and return the total.

    Given a sequence of as, combine them and return the total.

    If the sequence is empty, returns None. Otherwise, returns Some(total).

    Example:

    scala> import cats.kernel.instances.string._
    
    scala> Semigroup[String].combineAllOption(List("One ", "Two ", "Three"))
    res0: Option[String] = Some(One Two Three)
