I don't think this is the right way for WebSocket to move in.

[tsctx]

closed/

[KhafraDev]

@lpinca I'm not sure if you'd be interested in this or not.

[lpinca]

It is nice for portability but bufferutil seems to be faster in all cases.

[tsctx]

Since it must be copied to the memory area, bufferutil, which does not copy, has the advantage.

[lpinca]

Now that WebSocket is in Node.js core, we could add a Buffer.mask() and Buffer.unmask() implementation using SIMD instructions and exposing it for public usage similarly to how it was done for Buffer.isUtf8().

cc: @lemire @anonrig

Edit: Buffer.unmask() is not strictly needed. It is the same thing.

[lemire]

@lpinca Can you provide the specification for the functions?

[KhafraDev]

[lpinca]

@lemire for a possible API see https://github.com/websockets/bufferutil?tab=readme-ov-file#bufferutilmasksource-mask-output-offset-length. The last 3 parameters can be optional.

[lemire]

@lpinca @KhafraDev Thanks.
