This repository is the home of the cuid and cuid2 crates. The
original CUID standard is marked as deprecated
in favor of CUID2, but we intent to continue supporting v1 CUIDs
indefinitely, since their k-sortability is only insecure in specific
use-cases, while their sortability is quite useful in other
use-cases. cuid2
is provided as a separate crate because its
generated IDs have different semantics from cuid
, so it is not
necessarily a drop-in replacement.
If you are using the cuid
crate already, you can also use cuid2()
and related functions from that crate.
Please see the individual crates' READMEs for more information.
A flake.nix
file is provided for easy
installation of dependencies via the nix package manager. To start a shell with
all of the dependencies available, run:
nix develop
Or, if you are not yet using flakes, a shell.nix
shim is provided, so you can
do the same with
nix-shell
If you use direnv, the .envrc
file will automatically
source the nix packages into your shell (or editor environment, if you use a
direnv plugin).
