Description

I am hoping to support arch_target=Wasm32 as a compilation target for the rust arrow & datafusion packages.

My plan is to add compiler conditionals around any I/O features and libc dependent features of these two libraries.

My intent is to be able to use the apache arrow libraries in UDF style WASM functions which pass arrow memory references between the host (spark environment) and the WASM code
