A Rust EXI (Efficient eXtensible Interchange) implementation. EXI is a very compact binary XML representation.
This implementation does not need many dependencies and doesn't include any unsafe Rust.
⚠️ Only very basic decoding functionality currently implemented. Will crash, eat your laundry, etc when given any real-world EXI input.
| Item | Spec Link | State/Comments |
|---|---|---|
| Schema-less decoding | https://www.w3.org/TR/2014/REC-exi-20140211/#builtinGrammars | Decoding partially implemented |
| Options Decoding | https://www.w3.org/TR/2014/REC-exi-20140211/#options | ❌ Unimplemented, decoder will error if options are present in header |
| Schema-informed decoding | https://www.w3.org/TR/2014/REC-exi-20140211/#informedGrammars | ❌ Unimplemented |
| EXI Compression | https://www.w3.org/TR/2014/REC-exi-20140211/#compression | ❌ Unimplemented |
Currently unimplemented
- The EXI Spec is, for the most part, readable and complete - this implementation was written solely with reference to it and the primer (see below), without having to inspect already-existing implementations.
- The EXI Primer is a reasonable high level introduction to the concepts, although it perhaps under-explains some important aspects. In particular, the example step-by-step encoding/decoding are great, and I wish more specs included them!
