OrderedUUIDv1

UUID V1 Orderer

Ordering UUID V1 bytes by inserted timestamp for practical purposes. If you want to store UUID's sequentially in databases, you can use this library.

Requirement

Go 1.14 ~ 1.15, other versions not tested

Instalation

Add it in your project: go get github.com/MufidJamaluddin/uuidv1_orderer

How to Use

1. Ordering Existing UUID's

unorderedUuid := UUIDStringToBytes("c5db1800-ce4c-11de-a5e2-1b45123c6e98")

orderedUuid := ToOrderedUuid(unorderedUuid)

orderedUuidStr := UUIDBytesToString(orderedUuid)

// next, your logic

1. Transform Back to Standard UUID V1

orderedUuid := UUIDStringToBytes("11dece4c-c5db-1800-a5e2-1b45123c6e98")

standardUuidV1 := FromOrderedUuid(orderedUuid)

standardUuidV1Str := UUIDBytesToString(standardUuidV1)

// next, your logic

Notes

The differences explanation between ordered and standard UUID V1 is bellow

UUID V1 In String

Example: c5db1800-ce4c-11de-a5e2-1b45123c6e98

Meaning:

1. Timestamp 1de-ce4c-c5db1800 in c5db1800-ce4c-11de
2. Standard UUID version 1 in c5db1800-ce4c-(1)1de
3. Clock sequence a5e2
4. Standard MAC Address or Nonstandard Random IDs 1b45123c6e98

Ordered UUID V1

Reorder timestamp to it's origin form with UUID version on top.

Example: 11dece4c-c5db-1800-a5e2-1b45123c6e98
