- sealed trait Conjunction extends AnyRef
Type tag to choose a scalaz.Monoid instance that performs conjunction (
&&
) - sealed trait Disjunction extends AnyRef
Type tag to choose a scalaz.Monoid instance that performs disjunction (
||
) - sealed trait Dual extends AnyRef
Type tag to choose a scalaz.Monoid instance that inverts the operands to
append
before calling the natural scalaz.Monoid for the type.Type tag to choose a scalaz.Monoid instance that inverts the operands to
append
before calling the natural scalaz.Monoid for the type.Example:
import scalaz.{@@, Tag, Tags, Dual} import scalaz.std.string._ import scalaz.syntax.monoid._ import scalaz.Dual._ Dual("World!") |+| Dual("Hello, ") // "Hello, World!"
- sealed trait First extends AnyRef
Type tag to choose a scalaz.Monoid instance that selects the first non-
zero
operand to append. - sealed trait FirstVal extends AnyRef
Type tag to choose a scalaz.Semigroup instance that selects the first operand to append.
- sealed trait Last extends AnyRef
Type tag to choose a scalaz.Monoid instance that selects the last non-
zero
operand to append. - sealed trait LastVal extends AnyRef
Type tag to choose a scalaz.Semigroup instance that selects the last operand to append.
- sealed trait Max extends AnyRef
Type tag to choose a scalaz.Monoid instance that selects the greater of two operands, ignoring
zero
. - sealed trait MaxVal extends AnyRef
Type tag to choose a scalaz.Semigroup instance that selects the greater of two operands.
- sealed trait Min extends AnyRef
Type tag to choose a scalaz.Monoid instance that selects the lesser of two operands, ignoring
zero
. - sealed trait MinVal extends AnyRef
Type tag to choose a scalaz.Semigroup instance that selects the lesser of two operands.
- sealed trait Multiplication extends AnyRef
Type tag to choose a scalaz.Monoid instance for a numeric type that performs multiplication, rather than the default monoid for these types which by convention performs addition.
- sealed trait Parallel extends AnyRef
Type tag to choose a scalaz.Applicative instance that runs in parallel.
- sealed trait Zip extends AnyRef
Type tag to choose as scalaz.Applicative instance that performs zipping.
Type tag to choose as scalaz.Applicative instance that performs zipping.
