Sqids (pronounced "squids") is an open-source library that lets you generate YouTube-looking IDs from numbers. These IDs are short, can be generated from a custom alphabet and are guaranteed to be collision-free. Read more .
This is what they look like:

To encode & decode:
let sqids = Sqids::default();
let id = sqids.encode(&[1, 2, 3])?; // "86Rf07"
let numbers = sqids.decode(&id); // [1, 2, 3]Randomize IDs by providing a custom alphabet:
let sqids = Sqids::new(Some(Options::new(
Some("FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE".to_string()),
None,
None,
)))?;
let id = sqids.encode(&[1, 2, 3])?; // "B4aajs"
let numbers = sqids.decode(&id); // [1, 2, 3]Enforce a minimum length for IDs:
let sqids = Sqids::new(Some(Options::new(
None,
Some(10),
None,
)))?;
let id = sqids.encode(&[1, 2, 3])?; // "86Rf07xd4z"
let numbers = sqids.decode(&id); // [1, 2, 3]Read more at https://github.com/sqids/sqids-rust

The main use of Sqids is purely visual. If you'd like to use IDs instead of numbers in your webapp, Sqids could be a good choice:
