enarx-exec-wasmtime - the Enarx WebAssembly loader
enarx-exec-wasmtime is responsible for loading and running WebAssembly modules
inside an Enarx keep.
Users generally won't execute enarx-exec-wasmtime directly, but for test/debugging
purposes it can be used to run a .wasm file with given command-line
arguments and environment variables.
console
$ wat2wasm ../tests/wasm/return_1.wat

If no filename is given, enarx-exec-wasmtime expects to read the WebAssembly module
from file descriptor 3, so this would be equivalent:
console
$ RUST_LOG=enarx-exec-wasmtime=info RUST_BACKTRACE=1 cargo run -- 3< return_1.wasm
