Wasm has been steadily progressing and acquiring many new interesting features over the past years, and Rust continues to be a first-class citizen of the Wasm ecosystem. One such very interesting feature, is the multi-memory proposal.
Based on some very basic preliminary research though, it seems that actually using the feature in Rust will be tricky at best, since Rust (and LLVM for that matter, I think) views memory as a single contiguous region. This seems to be almost at odds with how Wasm implements multiple memories - as an additional immediate for the memory instructions.
My question is henceforth - are there yet any plans to implement this feature for the Rust+Wasm combo? Considering all the implications, I imagine this'll be a rather formidable task.
