Is there a method to generate empty UUID v4?

[fulviodenza]

Hi! I noticed there is a uuid.Nil for UUID v1 but no uuid.Nil (for example uuid.Nil4) for UUID v4 could be useful adding this method to the library? (I could also make a PR)

There's no difference in format between a v1 or v4, you could probably use this to generate an empty uuid

uuid/hash.go

Line 19 in 44b5fee

Nil UUID // empty UUID, all zeros

Alexi is correct. But just to be clear, the uuid.Nil is nil for every version (all zeros). v1 and v4 UUIDs themselves are very different in how the bits are computed and treated.
