ulid-rs

This is a Rust implementation of the ulid project which provides Universally Unique Lexicographically Sortable Identifiers.

Quickstart

// 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());

Optional features

• 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.
