## What it is
A pure Go package implementing Universally Unique Identifiers (UUIDs) per RFC 4122, supporting creation and parsing of versions 1-5. It offers 100% test coverage and benchmarks out of the box.

## Use cases
- generate random uuid v4 in go
- parse uuid from string
- create time-based uuid v1 from timestamp and mac address
- generate name-based md5 or sha1 uuids
- validate and format uuid strings in a go application

## When to choose
- you need a mature, widely-used Go UUID library supporting all RFC 4122 versions
- you want a pure Go implementation with no external dependencies
- you need both UUID generation and parsing with strong test coverage

## When to avoid
- you need UUID v6/v7 or newer RFC 9562 versions
- you prefer the actively maintained google/uuid package for new projects
- you are not working in Go

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, developer-tools
- domain: developer-tools
- platform: go, cross-platform
- tags: uuid, rfc4122, identifier-generation, algorithms
