rust-ksuid VS typeid

We maintain a couple of popular ksuid libraries[1][2] and use it, so we definitely like ksuid. Though one big issue with ksuid is that being 160bit means that it doesn't fit into native uuid types in databases (e.g. postgres), which means that they come with a performance penalty.

I wasn't going to post it here because it feels a bit small for a show HN, but then I figured: why not. :)

It's a pure Rust implementation of Segement's KSUID, and I created this library while working on Svix[0].

I haven't written any Rust for a while, so even though I have written quite a bit of Rust code in the past (see Etebase[1]), I'm a bit rusty (no pun intended).

Anyhow, I just wanted to share, and I'm hoping to get some feedback if you have any. :)

P.S, the package is tested for compatibility against the reference Go implementation.

I’ve seen this sort of design referred to as “typed IDs”: https://github.com/jetify-com/typeid

Doesn’t use the crockford encoding, but does is another one that minimises confusables.

But there is always TypeID in the meantime which uses UUIDv7 under the hood: https://github.com/jetify-com/typeid

Either way, I am in favor of prefixing and using alternative encodings, but it will need some time to figure out the best route. In the mean time, there are so many alternatives. TypeID, NanoID, ULID, etc. I even made my own quick one just for giggles: https://github.com/daegalus/snowflakes

If you want a type-prefixed UUIDv7 type, I can wholeheartedly recommend TypeID-JS: https://github.com/jetpack-io/typeid-js

Also available for a whole bunch of other languages: https://github.com/jetpack-io/typeid

UUIDv7 is UUIDv4-compatible (i.e. you can put a v7 UUID anywhere a v4 UUID would go, like in Postgres's UUID datatype) and is time-series sortable, so you don't lose that nice lil' benefit of auto-incrementing IDs.

And if you use something like TypeORM to define your entities, you can use a Transformer to save as plain UUIDv7 in the DB (so you can use UUID datatypes, not strings), but deal with them as type-prefixed strings everywhere else:

```

IMO, a good middleground is using schemes like TypeID[0], ulid[1], or KSUID[2] that provides a more compact and readable (base32) representation and provides better database locality (K-sortable).

If you do consider a GUID, I recommend the TypeID library we recently open-sourced. It has typing as part of the id, and it's based on UUIDv7. We think it has a few benefits over other GUIDs, including: + Easier to debug because of the type information + Type-safety can be enforced + Thanks to UUIDv7 is has good locality properties when used as the primary key of a database (unlike a completely random GUID) + We have a dotnet implementation in C# available

If you’re open to a globally unique identifier like UUID, I’d recommend you check out TypeIDs which we recently open sourced https://github.com/jetpack-io/typeid. They are based on the UUIDv7 standard, but add type information (like what Stripe does in their APIs), and we have a TypeScript implementation available.
