python-ksuid VS ulid

It's really fast, it makes writing secure and correct code easier, it's easier to deploy and distribute (one static binary), and it's a lot more fun. :)

Webhooks are really cool, and I absolutely love what they enable. They make the web compose-able, interconnected, and enable people to automate a lot of their work! Our goal is to make them easy, reliable, and consistent, so that more services offer them and they are easier to consume.

I'd love to hear your feedback! We've incorporated most of the comments we got the last time[0] (thanks again everyone!), and we would love to know how we can improve the product further. Got any suggestions?

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 created this library while working on Svix. We have a highly scalable and distributed environment there, which is where KSUIDs really shine.

These reasons are exactly why we started Svix[1] (we do webhooks as a service). I wish we existed to serve you guys back when you started working on it. :)

Hey everyone, my name is Tom, and I'm the founder of Svix (https://www.svix.com) - previously known as Diahook. Svix makes it easy for developers to send webhooks from their service using a simple API. Think Twilio or SendGrid but for webhooks.

Webhooks are how servers notify each other of events, so they are a key component of many APIs such as Stripe, Shopify, Slack, Dropbox and Github.

I really like ULID for this problem (e.g: https://github.com/ahawker/ulid)

- same number of bytes as UUID

- start with a date, so has great locality. Plus you get extra information in the uid that you can extract.

- can be created from an existing date or uuid, and exported to a uuid, so there is a migration path

As the author of a popular ULID implementation in python[1], the spec has no stewardship anymore. The specification repo[2] has plenty of open issues and no real guidance or communication beyond language implementation authors discussing corner cases. The monotonic functionality is ambiguous (at best) and is implemented differently per-languages [3].

Functionality, UUIDv7 might be the _same_ but the hope would be for a more rigid specification for interoperability.

Looks similar to ULID[0] (I am the author of a popular python implementation[1]).

It appears to have a similar constraint that two ID's generated within the same timestamp (ms, ns) have no strong guarantee of ordering. That might not be a deal breaker depending on your use case but something to consider.
