UUIDs

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")
UUIDs.uuid_versionFunction
uuid_version(u::UUID) -> Int

Inspects the given UUID and returns its version (see RFC 4122).

Examples

julia> uuid_version(uuid4())
4
