parseHexDash

fun parseHexDash(hexDashString: String): Uuid(source)

Parses a uuid from the standard hex-and-dash string representation as described in Uuid.toHexDashString.

This function is case-insensitive, and for a valid hexDashString, the following property holds:

val uuid = Uuid.parseHexDash(hexDashString)
assertEquals(uuid.toHexDashString(), hexDashString.lowercase())

The standard textual representation of uuids, also known as hex-and-dash format, is specified by RFC 9562 section 4.
