Hi, @makowskid

Why not just use Str::random?

Hi, @makowskid

Why not just use Str::random?

Please check the comments.
This method is very useful to add codes to important business objects (orders, flights bookings, transactions etc.):

• code is random (of course)
• can be spelt via phone
• designed to be interpreted by humans
• has only capital letters (easier to spell), capital-agnostic
• does not have confusing characters like 0/O, 1/l/I, etc
• (should be used with system-wide check for uniqueness)
• (its a bit like human-readable UUID)
