SNID for Rust

SNID is a polyglot sortable identifier protocol with UUIDv7-compatible ordering and extended identifier families. The Rust crate is the deterministic core implementation used for native Rust applications and by the Python bindings.

The canonical protocol specification lives in the repository at docs/SPEC.md. The Go implementation generates conformance vectors, and Rust validates those vectors as part of the release gate.

Install

cargo add snid

Quick Start

use snid::SNID;

let id = SNID::new();
let wire = id.to_wire("MAT");
let uuid = id.to_uuid_string();

Features

• UUIDv7-compatible 16-byte ordering.
• Base58 wire strings with atom prefixes.
• Extended families for spatial, neural, ledger, world, edge, capability, and blob identifiers.
• Optional data feature for serde-backed conformance and projection workflows.
