Ah - the Result is for error handling. So either:
1) Return arrow::Status from this function, and use the ARROW_ASSIGN_OR_RAISE
macro:
ARROW_ASSIGN_OR_RAISE(auto scalar, arrow::MakeScalar(...));
..., cp::literal(std::move(scalar)) ...
2) For experimentation purposes, just assume it'll succeed:
To follow up the discussion from the bi-weekly Arrow sync:
- JSON seems the most suitable candidate for the extension metadata.
E.g.: TensorArray
{"key": "ARROW:extension:name", "value": "tensor"},
{"key": "ARROW:extension:metadata", "value": "{'type': 'int64',
'shape': [3, 3, 4], 'strides': [12,
+1 (non-binding)
Updated to the release candidate and ran the test suite of our query
engine. Thanks a lot Andrew for the quick reaction.

I would like to propose a release of Apache Arrow Rust Implementation,
version 9.0.1.
This release candidate is based on commit:
e5003bf40bceb942c1c78cc2311e7d7a7e87ebf6 [1]
The proposed release tarball and signatures are hosted at [2].
The changelog is located at [3].

So I think I am getting close... now I have
cp::Expression predicate = cp::call(
"equal",
{...}
cp::literal(arrow::MakeScalar(arrow::time64(arrow::TimeUnit::NANO), time))}
);
Another question - what is the correct way of creating a constant Scalar
that represents a time64 from a string in C++ (e.g. "10:00:00") ?
I am trying to use cp::literal(arrow::MakeScalar(...)) but not sure what to
fill in the body of MakeScalar

Hello,
Did some more work on this. Follow up question on this:
I am doing a
{cp::call("cast",
{cp::field_ref("time_ns")},
cp::CastOptions::Safe(arrow::timestamp(arrow::TimeUnit::NANO, timezone)))},
And got:
NotImplemented: Unsupported cast
Testing has found a critical issue[1] in RC1. I'll be creating an RC 2
shortly with the fix.
Sorry about that,
Andrew
