cc @Fokko do you think this is a bug on the rust side?

[kevinjqliu]

TruncateTransform(10), for (BinaryType(), b"\x8e\xd1\x87\x01"), fails

[Fokko]

Yes, looks like it. Let me submit a patch, thanks!

[kevinjqliu]

nightly build doing its job :)

[kevinjqliu]

all good here, thanks for the quick fix @Fokko
