The Rust ecosystem is mature enough for a CHD decoder but there are some critical lacking pieces for write operations, all of them to do with codecs. - [x] FLAC Encoder (https://crates.io/crates/flacenc) - [x] Mature LZMA Encoder that allows writing raw chunks (https://docs.rs/lzma-rust2/latest/lzma_rust2/struct.LzmaWriter.html) - [x] Deflate Encoder (https://crates.io/crates/flate2) - [ ] Huffman Encoder (needs to be hand-rolled)
