Class FFIRecordBatch

Access the pointer to the ArrowArray struct. This can be viewed or copied (without serialization) to an Arrow JS RecordBatch by using arrow-js-ffi. You can access the WebAssembly.Memory instance by using wasmMemory.

Example:

import { parseRecordBatch } from "arrow-js-ffi";

const wasmRecordBatch: FFIRecordBatch = ...
const wasmMemory: WebAssembly.Memory = wasmMemory();

// Pass `true` to copy arrays across the boundary instead of creating views.
const jsRecordBatch = parseRecordBatch(
  wasmMemory.buffer,
  wasmRecordBatch.arrayAddr(),
  wasmRecordBatch.schemaAddr(),
  true
);
Copy

Access the pointer to the ArrowSchema struct. This can be viewed or copied (without serialization) to an Arrow JS Field by using arrow-js-ffi. You can access the WebAssembly.Memory instance by using wasmMemory.

Example:

import { parseRecordBatch } from "arrow-js-ffi";

const wasmRecordBatch: FFIRecordBatch = ...
const wasmMemory: WebAssembly.Memory = wasmMemory();

// Pass `true` to copy arrays across the boundary instead of creating views.
const jsRecordBatch = parseRecordBatch(
  wasmMemory.buffer,
  wasmRecordBatch.arrayAddr(),
  wasmRecordBatch.schemaAddr(),
  true
