Detailed Description

The Uuid class is a replacement for QUuid to get UUID strings without {} braces.

This class implements an RFC4122 compliant UUID of type "DCE" in Version 4 (random UUID). Other types and/or versions of UUIDs are considered as invalid. The characters in a UUID are always lowercase.

A valid UUID looks like this: "d79d354b-62bd-4866-996a-78941c575e78"

Note

This class guarantees that only Uuid objects representing a valid UUID can be created (in opposite to QUuid which allows "Null UUIDs")! If you need a nullable UUID, use tl::optional<librepcb::Uuid> instead.
