This is a Rust implementation of the ulid project which provides Universally Unique Lexicographically Sortable Identifiers.
```rust use ulid::Ulid;
// Generate a ulid let ulid = Ulid::new();
// Generate a string for a ulid let s = ulid.to_string();
// Create from a String let res = Ulid::from_string(&s);
assert_eq!(ulid, res.unwrap()); ```
std (default): Flag to toggle use of std and rand. Disable this flag for #[no_std] support.serde: Enables serialization and deserialization of Ulid types via serde. ULIDs are serialized using their canonical 26-character representation as defined in the ULID standard. An optional ulid_as_u128 module is provided, which enables serialization through an Ulid's inner u128 primitive type. See the documentation and serde docs for more information.uuid: Implements infallible conversions between ULIDs and UUIDs from the uuid crate via the std::convert::From trait.Benchmarks were run on my desktop (Win 10/WSL2 Ubuntu; Ryzen 7 5950x). Run them yourself with cargo bench.
