iex> Diffo.Uuid.trailing_uuid4(nil) nil

Generates a uuid4

Ensures the supplied uuid is valid uuid4, if not creates one.

Examples

iex> validated = Diffo.Uuid.uuid4("4cc5b107-0ff3-4bda-80e1-e4264cbaf868") iex> validated "4cc5b107-0ff3-4bda-80e1-e4264cbaf868"

iex> generated = Diffo.Uuid.uuid4(nil) iex> valid = Diffo.Uuid.uuid4?(generated) iex> valid true

Tests whether the uuid is uuid4.

Examples

iex> Diffo.Uuid.uuid4?("746e465b-3969-460a-980f-af69c9ab248a") true

iex> Diffo.Uuid.uuid4?("9a4cdc44-ca5a-11ef-9cd2-0242ac120002") false

iex> Diffo.Uuid.uuid4?(nil) false

Tests whether the uuid is uuid4 or nil.

Examples

iex> Diffo.Uuid.uuid4_or_nil?("746e465b-3969-460a-980f-af69c9ab248a") true

iex> Diffo.Uuid.uuid4_or_nil?("9a4cdc44-ca5a-11ef-9cd2-0242ac120002") false

iex> Diffo.Uuid.uuid4_or_nil?(nil) true
