Create a bytevector from a list of bytes

Create an empty bytevector

Generate a random 4-byte mask key Returns a bytevector of length 4

Apply XOR mask to data Returns new bytevector with masked data

Encode a WebSocket frame Client frames MUST be masked per RFC 6455

Encode a text frame (always masked for client)

Encode a binary frame (always masked for client)

Encode a close frame with optional status code

Encode a ping frame

Encode a pong frame (usually echo of ping payload)

Encode a text frame for server-to-client delivery (unmasked).

Encode a binary frame for server-to-client delivery (unmasked).

Encode a close frame from the server (unmasked). Optional close code per RFC 6455 §7.4.

Encode a ping frame from the server (unmasked).

Encode a pong frame from the server (unmasked). Pong payload must equal the originating ping's payload.
