How does this work with things like WASI--back when I did WASM things I recalled that WASM relies on imported functions for things like Io, etc. so what functions is the Docker runtime providing here?
I am very confused about how wasi calls work in something like wasmer or wasmtime vs a browser. My guess is the former expose a runtime directly to the wasm executable, and in the browser this has to be done via autogenerated js bindings?
