run-length-encode-rs

Entry for BBC Academy summer '22 coding challenge.

Building

1. Install rust.
2. Build the executable with cargo build --release. By default it will be located in target/release/rle.

Usage

rle mono <inputfile>
    monochrome image encoding

rle grey <inputfile>
    greyscale (hex shade) image encoding

rle grey n <inputfile>
    greyscale (hex shade) image encoding with a compression factor (0 to 15)

Input files must use the bespoke kata file format.

Future work

• Mono/hex decoders
• Benchmarking
• Divide & Conquer encoding: can it be done faster if we parallelise encoding sections of the file?
