WebAssembly BigInti64 conversion in JS API

June 16, 2020 ยท View on GitHub

This proposal has been merged into the main specification.

With the changes in this repository, BigInts have support for bidirectionally converting to 64-bit integer WebAssembly values, which appears as

  • Parameters and return values to exported WebAssembly functions
  • Parameters and return values to host functions
  • Imported and exported globals

BigInts can be read or written from WebAssembly memory using the BigInt proposal's BigInt64Array or BigUint64Array; no additional support is needed.
