# base64uuid > `Base64Uuid` type for representing base64url-encoded UUIDs. The main motivation for using these is that their representation is slightly more compact compared to standard UUID string representation, and they look a bit better in URLs. In addition, any UUIDs generated by this crate are chosen such that their string representations do not start with a dash (`-`), in order to avoid conflicts if they're used as command-line arguments. ## Feature flags - `creation`: Allows creating `Base64Uuid` and `Uuid` directly (enabled by default) - `fp-bindgen`: Allows using `Base64Uuid` within [`fp-bindgen`](https://github.com/fiberplane/fp-bindgen) structs
