A few of the arrow kernels rely on macros to iterate over values using a common `.value()` function, but: * this function is safe on some array types (string, binary), but unsafe on other array types (primitive - although it is not currently marked as such) * this forces iteration by index, which requires unsafe code to guarantee bounds checks are avoided (which can be dangerous for multi-array operations) This PR is an experiment with a TypedArray trait, which provides access to array values (along with associated types describing those values). This will NOT remove the need for downcasting, as the associated types aren't object safe. But it should be sufficient to allow simple processing of values from multiple array types using a generic function instead of a macro. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
