// * `engine` - a previously created engine which will drive allocations and

// * `wat` - this it the input buffer with the WebAssembly Text Format inside of
//   it. This will be parsed and converted to the binary format.
// * `ret` - if the conversion is successful, this byte vector is filled in with
//   the WebAssembly binary format.
// * `error_message` - if the conversion fails, this is filled in with a
//   descriptive error message of why parsing failed. This parameter is
//   optional.
//
// Returns `true` if conversion succeeded, or `false` if it failed.
