scala - Simple example of Either, Left, Right with scalaz -


how can implemented using scalaz? example taken here

object myobject {    def dividexbyy(x: int, y: int): either[string, int] = {     if (y == 0) left("cannot divide 0")     else right(x / y)    }    def main(args: array[string]) {      println(dividexbyy(12, 3))     println(dividexbyy(12, 0))      dividexbyy(12, 3) match {       case right(a) => println(s"we got: ${a}")       case left(b) => println(s"we got: ${b}")     }   } } 

import scalaz.{-\/, \/, \/-}  object myobject {    def dividexbyy(x: int, y: int): either[string, int] = {     if (y == 0) left("cannot divide 0")     else right(x / y)    }    def dividexbyyscalaz(x: int, y: int): \/[string, int] = {     if (y == 0) -\/("cannot divide 0")     else \/-(x / y)   }    def main(args: array[string]) {      println(dividexbyy(12, 3))     println(dividexbyy(12, 0))      dividexbyy(12, 3) match {       case right(a) => println(s"we got: ${a}")       case left(b) => println(s"we got: ${b}")     }      println("working scalaz")      println(dividexbyyscalaz(12, 3))     println(dividexbyyscalaz(12, 0))      dividexbyyscalaz(12, 3) match {       case -\/(a) => println(s"we got: ${a}")       case \/-(b) => println(s"we got: ${b}")     }   } }

Image
is possible retrieve eta google's distancematrix api (or alternative api). fyi, eta different duration, when using public transport. following example clarify request. when leave on friday @ 8.15 i'll able catch train @ 8.30 , arrive @ 9.00 am. google says duration 30 minutes. however, when leave on saturday @ 8.15 i'll able catch first train @ 9.00 , arrive @ 9.30 am. google still says duration 30 minutes, means ignore delay. google map supports functionality there api around giving me eta instead of duration. can see, distance-matrix' response no good. clarifying question little. eta estimated time of arrival , it's clear user wants know entire duration of transport (including waiting time public transport).
