scala-ulid is a library for ULID.
Add the following to your sbt build (2.11.x, 2.12.x, 2.13.x):
val version = "..."
libraryDependencies += Seq(
"com.chatwork" %% "scala-ulid" % version
)val ulid = ULID.generate()
val str = ulid.asString
println(str) // 01EQWGKT1S68Y9YM5TV34RQVQA
ULID.parseULID(str).foreach{ uild =>
println(ulid) // 01EQWGKT1S68Y9YM5TV34RQVQA
}
val bytes = uild.toBytes
ULID.fromBytes(bytes).foreach { ulid =>
println(ulid) // 01EQWGKT1S68Y9YM5TV34RQVQA
