Question: Having trouble getting ref-array to work with ref-struct

Declaring an array type such as

var uint8ArrayType = refArray(ref.types.uint8);

and then using this type in a struct declaration such as

var mystruct = refStruct({
arr : uint8ArrayType(16)
});

will cause ref to fail on coerceType with the error message

AssertionError: could not determine a proper "type" from: [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]
at Object.coerceType (.../node_modules/ffi/node_modules/ref/lib/ref.js:389:3)

I seems that the assertion fails due to either indirection or size being unavailable.

Is this due to a general incompatibility, which I doubt, or due to the fact that I am using some old version of either of one of the libs, namely ref-array or ref?

TIA

You need to define your arr array type with the size specified as the second argument. Do it like this:

var mystruct = refStruct({
  arr: refArray(ref.types.uint8, 16)
});

Believe it or not, but just before I read your comment I realized that I created an instance of the array type instead of passing the type... Thanks so much for the quick reply and keep up your tremendous work!

Glad you got everything sorted out. Rock on!
