How to return a byte array as a Python bytes object?

[nurpax]

I'm creating bindings that'd need to return some arrays of arbitrary byte buffers (uint8_t arrays) as a Python bytes object. But I can't quite figure out where to start.

One alternative would be to return an ndarray instead, but the bindings are used in a context that otherwise expects to see bytes objects. The nb::bytes() constructors seem to only support constructing from C strings but.

Good catch, this is now fixed in 18376ff
