Parsing and Generating GUIDs in GPT Header Fields
A while back I wrote about the binary format of GUIDs in GPT headers. Based on some examples I reverse-engineered conversion between a 128-bit integer on disk, and a UUID’s fields.
I’ve likely duplicated some logic from winapi. In the uuid crate, a feature can be enabled to include code for converting UUIDs into GUIDs (defined in winapi), but it only works when the target is windows (a requirement of winapi).
