# Agenda for `mr-ulid`

These are some simple notes on what still needs to be done or could be done.
It is not certain what will be implemented and what will not.


## Todo /  Need fix

- Error types for invalid lengths are used for strings and slices. Resulting error messages are wrong.


## Evaluate

- Reconsider error type.


## Ideas, Thoughts

- Drop `ZeroableUlid` entirely.
- Consider `no_std` support
