    // These enum values are here so that TypeScript can narrow the type signatures further
    // beyond the base Arrow types. The base Arrow types include metadata like bitWidths that
    // impact the type signatures of the values we return. For example, the Int8Vector reads
    // 1-byte numbers from an Int8Array, an Int32Vector reads a 4-byte number from an Int32Array,
    // and an Int64Vector reads a pair of 4-byte lo, hi int32s, and returns them as a zero-copy
    // slice from an underlying Int32Array. Library consumers benefit by doing this type narrowing,
    // since we can ensure the types across all public methods are propagated and never bail to `any`.
    // These values are _never_ actually used at runtime, and they will _never_ be written into the
    // flatbuffers metadata of serialized Arrow IPC payloads.
