Which parts of the source are used for parsing and sending frames (for compilation to WASM/JavaScript)?

[guest271314]

I'm working on a WebSocket server run from the browser in an Isolated Web App using WICG Direct Sockets TCPServerSocket.

Right now I'm stuck on parsing continuation frames to handle messages greater than 65536.

I downloaded and built this repository. The code works as expected.

I don't need the network connection or handshake parts. Just the frame parsing and sending parts. The target client will be WebSocketStream in Chromium-based browsers.

Which specific sections of code handle parsing frames from a raw request?
