Uuid25: 25-digit case-insensitive UUID encoding

Crates.io License

Uuid25 is an alternative UUID representation that shortens a UUID string to just 25 digits using the case-insensitive Base36 encoding. This library provides functionality to convert from the conventional UUID formats to Uuid25 and vice versa.

use uuid25::Uuid25;

// convert from/to string
let a = Uuid25::parse("8da942a4-1fbe-4ca6-852c-95c473229c7d")?;
assert_eq!(a, "8dx554y5rzerz1syhqsvsdw8t");
assert_eq!(a.to_hyphenated(), "8da942a4-1fbe-4ca6-852c-95c473229c7d");

// convert from/to 128-bit byte array
let b = Uuid25::from([0xff; 16]);
assert_eq!(b, "f5lxx1zz5pnorynqglhzmsp33");
assert_eq!(b.to_bytes(), [0xff; 16]);

// convert from/to uuid crate's Uuid value (enabled by uuid feature)
let uuid_crate = uuid::uuid!("f38a6b1f-576f-4c22-8d4a-5f72613483f6");
let c = Uuid25::from(uuid_crate);
assert_eq!(c, "ef1zh7jc64vprqez41vbwe9km");
assert_eq!(uuid::Uuid::from(c), uuid_crate);

// convert from/to other popular textual representations
let d = [
    Uuid25::parse("e7a1d63b711744238988afcf12161878")?,
    Uuid25::parse("e7a1d63b-7117-4423-8988-afcf12161878")?,
    Uuid25::parse("{e7a1d63b-7117-4423-8988-afcf12161878}")?,
    Uuid25::parse("urn:uuid:e7a1d63b-7117-4423-8988-afcf12161878")?,
];
assert_eq!(d, ["dpoadk8izg9y4tte7vy1xt94o"; 4]);

let e = Uuid25::parse("dpoadk8izg9y4tte7vy1xt94o")?;
assert_eq!(e.to_hex(), "e7a1d63b711744238988afcf12161878");
assert_eq!(e.to_hyphenated(), "e7a1d63b-7117-4423-8988-afcf12161878");
assert_eq!(e.to_braced(), "{e7a1d63b-7117-4423-8988-afcf12161878}");
assert_eq!(e.to_urn(), "urn:uuid:e7a1d63b-7117-4423-8988-afcf12161878");

// create value in const context
const K: Uuid25 = Uuid25::parse_unwrap("ae5f2947-0784-48de-af26-690bc03b1f22");
assert_eq!(K, "abmwj0hrnat6qdyswurn714bm");

Integration with other crates

This crate implements conversion traits from/into UUID types of other popular crates. To enable such conversion traits, turn on the corresponding crate features. For example, to enable conversion from/into uuid::Uuid, put the following entries in Cargo.toml:

[dependencies]
uuid   = { version = "<version>", features = ["v4"] }
uuid25 = { version = "<version>", features = ["uuid"] }

And then:

use uuid25::Uuid25;

let x: Uuid25 = uuid::Uuid::new_v4().into();
println!("{}", x); // e.g. "6n7pvwv8r54xycmuby0pp1q8a"

let y: uuid::Uuid = x.into();
println!("{}", y); // e.g. "703d4a3e-5f1a-473e-90dd-fe20c883780a"

Crate features

Default features:

  • std integrates this crate with std and enables integration with std::string::String and std::error::Error. Note that this crate does not rely a lot on std and most of the functionality of this crate is still available under no_std environments.

Optional features:

  • serde enables serialization/deserialization of Uuid25 values through serde
  • uuid enables conversion traits from/into uuid::Uuid
  • bson enables conversion traits from/into bson::Uuid
  • uuid7 enables conversion traits from/into uuid7::Uuid
