Experimental WebAssembly

Experimental wrapper to load a WebAssembly program. Returns a list of exported functions. This will probably be moved into it's own package once WebAssembly matures.

wasm(data)

wasm_features()

Arguments

data

either raw vector or file path with the binary wasm program

Details

The wasm_features() function uses the wasm-feature-detect JavaScript library to test which WASM capabilities are supported in the current version of libv8.
