Raw

This crate provides the Euui struct.

This type represents a unique identifier which is 4 times bigger than UUIDs and GUIDs.
So, an EUUI is 512 bits or 64 bytes. It can be read as 4xu128, 8xu64 or 64xu8.

A raw hexadecimal string representing an EUUI is 128 characters wide.
A formatted hexadecimal string representing an EUUI is 131 characters wide (two "-" and one "\n").

You can create :

  • a zero Euui with Euui::default,
  • or, a random one with Euui::random.

Then, use :

  • Euui::format to display it as 4 u128s or Euui::.to_string to get the whole hexadecimal string,
  • or, Euui::u128 or Euui::to_be_guids to reach for individual u128s,
  • or, Euui::u64 to reach for individual u64s,
  • or, Euui::u8 or Euui::to_be_bytes to reach for individual u8s.
