bcur

A Rust implementation of Uniform Resources (URs).

URs encode binary payloads as URI-friendly strings for QR codes and unreliable channels, using bytewords and fountain codes for multi-part transfer.

Status (0.2)

Transport: bytewords + fountain + multi-part UR + DecoderLimits.
Typed dCBOR: feature = "dcbor" (Ur, traits, multipart wrappers; implies std).

Features

no_std + alloc: --no-default-features.

Quick start

use bcur::{Decoder, Encoder};

let data = b"Ten chars!".repeat(10);
let mut encoder = Encoder::bytes(&data, 5).unwrap();
let mut decoder = Decoder::default();
while !decoder.complete() {
    let part = encoder.next_part().unwrap();
    decoder.receive(&part).unwrap();
}
assert_eq!(decoder.message().unwrap().as_deref(), Some(data.as_slice()));

Typed (feature = "dcbor"):

use bcur::Ur;

let ur = Ur::new("test", vec![1, 2, 3]).unwrap();
assert_eq!(ur.string(), "ur:test/lsadaoaxjygonesw");
