uuid

A small and tested library to generate uuid version 4 & 7

Installation

Add uuid_v47 to the dependencies in your rebar.config:

{deps, [{uuid_v47, "1.2.1"}]}
% or
{depts, [{uuid_v47, {git, "https://github.com/Eptwalabha/erl-uuid.git", {tag, "v1.0.1"}}}]}

then fetch and compile the dependencies of your project:

rebar3 compile --deps_only

That's it, you're good to go.

Usage

> uuid:v4().
"ef381427-61a2-4201-bd97-21b295bea06f"
> uuid:v7().
"019c353b-c7e8-7fb6-a387-cd2c14626505"

Using seed

use crypto:rand_seed_alg to seed the uuid

> crypto:rand_seed_alg(crypto_aes, <<"my seed">>).
> uuid:v4().
"86bf7f93-c61f-45b3-b94e-c871dca40304"
> crypto:rand_seed_alg(crypto_aes, <<"my seed">>).
> uuid:v4().
"86bf7f93-c61f-45b3-b94e-c871dca40304"

[!TIP] To some extends, it also works with uuid:v7/0
