/**
|
|
* 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 non-negative enum values 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.
