youid

Generate and parse UUIDs.

gleam add youid

import youid/uuid

pub fn main() {
  // Generate a universally-unique identifier
  let id = uuid.v7()

  // Convert it to the standard text format
  uuid.to_string(id)
  // -> "019d449c-2c82-71bb-b4bf-6505df7ad7c2"

  // Convert it a URL-safe compact text format
  uuid.to_base64(id)
  // -> "AZ1EnCyCcbu0v2UF33rXwg"
}

Spec conformant UUID decoding for v1, v2, v3, v4, v5, and v7.

Unless you have a specific reason otherwise, you probably either want the random v4 or the time-based v1 or v7 versions.
