id-forge 0.9.3 - Docs.rs

What it does

Every project needs unique identifiers. Today's options force you to mix and match crates: uuid for UUIDs, ulid for ULIDs, snowflake-rs for Snowflakes, nanoid for NanoIDs. Each has its own conventions, MSRV, and dependency tree.

id-forge puts every common ID scheme in one crate with zero runtime dependencies and MSRV 1.75.

Quick start

use id_forge::{uuid::Uuid, ulid::Ulid, snowflake::Snowflake, nanoid};

let id = Uuid::v4();                     // "f47ac10b-58cc-4372-..."
let id = Uuid::v7();                     // time-ordered UUID
let id = Ulid::new();                    // "01H6X3VPK..."
let gen = Snowflake::new(1);             // worker ID = 1
let id: u64 = gen.next_id();             // 64-bit snowflake
let id = nanoid::generate();             // "VNqJgL1..."
let id = nanoid::with_length(8);         // shorter NanoID

Schemes supported

Scheme	Size	Sortable	Distributed-safe	Use case
UUID v4	128 bits	No	Yes	Random identifiers, no time component needed
UUID v7	128 bits	Yes	Yes	Time-ordered random ID (preferred over v4 for DB primary keys)
ULID	128 bits	Yes	Yes	Sortable, URL-friendly identifiers
Snowflake	64 bits	Yes	Yes (with worker ID)	Fits in `u64`, time-ordered, suited for high-throughput
NanoID	configurable	No	Yes	URL-safe short IDs, configurable alphabet

Feature flags

id-forge = { version = "0.9.3", default-features = false } # nothing (compile errors if you use anything)
id-forge = { version = "0.9.3", default-features = false, features = ["uuid"] }  # just UUIDs
