Short Unique IDs in Zig

What is Sqids?

Sqids (pronounced "squids") is an open-source library that lets you generate short unique identifiers from numbers. These IDs are URL-safe, can encode several numbers, and do not contain common profanity words. Read more .

This is what they look like:

Quick encode & decode example:

const s = try sqids.Sqids.init(allocator, .{})
const id = try s.encode(&.{1, 2, 3}); // "86Rf07"
const numbers = try s.decode(id); // {1, 2, 3}

If IDs are too short, you can pad them to a certain length:

const s = try sqids.Sqids.init(allocator, .{.min_length = 10})
const id = try s.encode(&.{1, 2, 3}); // "86Rf07xd4z"
const numbers = try s.decode(id); // {1, 2, 3}

Create unique IDs by shuffling the alphabet:

const s = try sqids.Sqids.init(allocator, .{.alphabet = "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt"})
const id = try s.encode(&.{1, 2, 3}); // "XRKUdQ"
const numbers = try s.decode(id); // {1, 2, 3}
