…type/parse_castype_args for the vector type. If we can get serde working we might be in good shape.

There was a problem hiding this comment.
Note the explicit assumption here that each element in the vector has a serialized form that is 4 bytes long. This is fine for the initial rollout (which will only include server-side support of float vectors) but needs to be generalized... although it should be noted there's some significant conversation on the Java equivalent of this PR about how to generalize that.

This PR has been vetted by significant use of these changes in internal work on vector support. |
