uuid4s

uuid4s is yet another functional uuid for Scala. It tries to be typeful and purely functional. Java UUID’s aren’t safe and are not referentially transparent. The objetive of this library is provide a set of tools for interacting with FUUID’s.

Installation

Add the following to your build.sbt.

// For Scala 2.11, or 2.12
libraryDependencies += "org.pure4s" %% "uuid4s" % "0.1.3"

Rationale

1. It's easy to use.
2. It does not force a specific target context. You can run your computations in any type F[_] that has an instance of cats-effect's Sync[F].
3. It has documentation.
4. It's modular.

Modules

Module name	Description	Version
uuid4s	The core functionality of uuid4s	0.1.3
uuid4s-fast	Use fast uuid fast-uuid	0.1.3
uuid4s-circe	Encode and decode HTTP entities with Circe	0.1.3
uuid4s-http4s	Run your HTTP requests with http4s http4s	0.1.3

Usage

Example 1:

import java.util.UUID
import cats.effect.IO
import cats.implicits._
import org.pure4s.uuid4s.FUUID
import org.pure4s.uuid4s.implicits._

object BasicExampleMain extends App {

  //Parsing
  val uuid1: UUID =
    FUUID[IO].fromString("7cfb70a9-0764-4851-a28c-309393aea2eb").unsafeRunSync()

  //Generating
  val uuid2: UUID = FUUID[IO].random.unsafeRunSync()

  //Comparing
  val result1: Boolean = uuid2 < uuid1
  val result2: Boolean = uuid2 <= uuid1
  val result3: Boolean = uuid1 > uuid2
  val result4: Boolean = uuid1 >= uuid2
  val result5: Boolean = uuid1 === uuid1
}
