It is always a topic for discussion, so I want to create a rough guideline how we should serialize/deserialize IO in web assembly.
- Numbers use whatever feels most natural to the exercise ([fiu][8,16,32,64])
- Strings are always transferred as offset/length with the content UTF8-encoded in linear memory
- Boolean arrays will by serialized as bit arrays
- Number arrays will be serialized as TypedArray, otherwise handled like strings
- String arrays that can be delimited by a line break will be serialized as a single string and have a line break after every line (including the last one) - this only applies to the output if it is expected in form of an array
- Multi-dimensional arrays will be flattened and have the dimension’s lengths as an optional values along offset and length (except if the dimension’s length is already known, e.g. in Series)
- Objects and arbitrary dimension arrays are (de)-serialized as JSON
Please add your opinions!
