Float array pointer

[liquidg3]

Firstly, great work!

We've almost completely replaced ffi-napi in our platform with ffi-rs.

Here is some background on us if you're interested: https://lumenalabs.com

We're utilizing some biosensors and Lab Streaming Layer (https://labstreaminglayer.org/#/) to track different biometrics.

We are so close, but the function we are trying to call is here:

https://github.com/sccn/liblsl/blob/master/src/lsl_outlet_c.cpp#L40C1-L42C2

LIBLSL_C_API int32_t lsl_push_sample_ft(lsl_outlet out, const float *data, double timestamp) {
    return out->push_sample_noexcept(data, timestamp);
}

And we can't seem to get it to call in a way that sends any data to our neuro-engine.

Here is how we have it defined(...):

...
lsl_push_sample_ft: {
    library: 'lsl',
    retType: DataType.Void,
    paramsType: [DataType.External, DataType.DoubleArray, DataType.Double],
 },
...

It's the second paramType - the function in c++ is defined with a pointer to a float array, which we're assuming is the issues. We've tried every DataType.*Array we can find in hopes that something would be coerced to functioning, but we can't get it.

Any suggestions or enhancements would make our day!

Thanks so much!

i wlill handle the issue at later

It seems there can not use doubleArray type transform to floatArray, i will support DataType.floatArray ASAP

[zhangyuang]

Support DataType.floatArray in ffi-rs@1.0.63, you can try with the latest version

That worked! Epic work! I meant to get back to you sooner actually, my bad!

I am glad that the library can help you out
