cdrle

Calldata RLE — a simple, bounded run-length encoding specialized for Ethereum calldata.

  • Literals: any byte != 0x00
  • Runs: (0x00, CONTROL) where bit7=0→zeros, bit7=1→0xFF, low7=(len-1)
  • Caps: zeros 1..=128, 0xFF 1..=32
  • Encoder XOR-negates the first 4 bytes of the compressed stream to aid fallback routing; decoder un-negates on read.

Usage

let input = b"\x00\x00\x00\x00*\xff\xff\xff\x01\x02\x03\x00\xff\x00\xaa\xbb\x00\xff";
let compressed = cdrle::compress(input);
let decompressed = cdrle::decompress(&compressed).unwrap();
assert_eq!(input, &decompressed[..]);
