Build Status GoDoc Go Report Card


Globally unique identifiers offer a quick means of generating non-colliding values across a distributed system. For this implemenation, RFC 4122 governs the desired behavior.

What's in a name?

You have likely already noticed that RFC and some implementations refer to these structures as UUIDs (Universally Unique Identifiers), where as this project is annotated as GUIDs (Globally Unique Identifiers). The name Guid was selected to make clear this project‘s ties to the .NET struct Guid. The most obvious relationship is the desire to have the same format specifiers available in this library’s Format and Parse methods as .NET would have in its ToString and Parse methods.
