Ulid
On this page
A sortable unique identifier: 26 capital letters and digits.
Use it when you receive ids in this form. For your own records, Uuid is what Jadpo generates.
Shape
One value, held as text in one set form, with no parts: 7ZZZZZZZZZZZZZZZZZZZZZZZZZ.
Example
Ulid("01ARZ3NDEKTSV4RRFFQ69G5FAV")Ulid(raw) checks the text, and text that isn't one breaks the format rule.
text.parse(raw, as: Ulid) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 8ZZZZZZZZZZZZZZZZZZZZZZZZZ, 01arz3ndektsv4rrffq69g5fav or 01ARZ3NDEKTSV4RRFFQ69G5FAI.
Good to know
- It is upper case. The first character can't be above
7. ==tells you whether two are the same.<andlist.sort_bydon't take it.
In JSON
A string, in a request, a response or json.write:
"01ARZ3NDEKTSV4RRFFQ69G5FAV""7ZZZZZZZZZZZZZZZZZZZZZZZZZ"
