> brotli, a magmalake tin: A Mojo binding to libbrotli, the last of the seven Parquet page codecs.

[magmalake](https://magmalake.dev/) [brotli](https://magmalake.dev/s/brotli)

A Mojo binding to libbrotli, the last of the seven Parquet page codecs. Bound rather than written: RFC 7932 needs two prefix-code forms, context maps, block-type switching, a distance cache and a 122 KB static dictionary with 121 word transforms that are part of the format itself.

## Works today

- One-shot compress and decompress, quality 0–11
- A Brotli stream records no uncompressed size, so sized and unsized decoding are separate calls
- The shim is dlopen'd once, not per call

Checked against CPython's brotli package, on streams it produced and this one had never seen
