UUIDs.uuid1Function

uuid1([rng::AbstractRNG=GLOBAL_RNG]) -> UUID

Generates a version 1 (time-based) universally unique identifier (UUID), as specified by RFC 4122. Note that the Node ID is randomly generated (does not identify the host) according to section 4.5 of the RFC.

Examples

julia> rng = MersenneTwister(1234);

julia> uuid1(rng)
UUID("cfc395e8-590f-11e8-1f13-43a2532b2fa8")

UUIDs.uuid4Function

uuid4([rng::AbstractRNG=GLOBAL_RNG]) -> UUID

Generates a version 4 (random or pseudo-random) universally unique identifier (UUID), as specified by RFC 4122.

Examples

julia> rng = MersenneTwister(1234);

julia> uuid4(rng)
UUID("196f2941-2d58-45ba-9f13-43a2532b2fa8")
