/**
* Main data type enumeration.
*
* Data types in this library are all *logical*. They can be expressed as
* either a primitive physical type (bytes or bits of some fixed size), a
* nested type consisting of other data types, or another data type (e.g. a
* timestamp encoded as an int64).
*
* **Note**: Only enum values 0-17 (NONE through Map) are written to an Arrow
* IPC payload.
*
* The rest of the values are specified here so TypeScript can narrow the type
* signatures further beyond the base Arrow Types. The Arrow DataTypes include
* metadata like `bitWidth` that impact the type signatures of the values we
* accept and 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 32-bit integers as a zero-copy slice from the
* underlying `Int32Array`.
*
* Library consumers benefit by knowing the narrowest type, since we can ensure
* the types across all public methods are propagated, and never bail to `any`.
* These values are _never_ used at runtime, and they will _never_ be written
* to the flatbuffers metadata of serialized Arrow IPC payloads.
