Overview

Note:

You should NEVER use this class directly - use Client or Server subclasses instead, as they contain additional frame options(i.e. Client-side masking in draft 04)

Construct or parse outgoing WebSocket Frame.

Examples:

frame = WebSocket::Frame::Outgoing::Server.new(version: @handshake.version, data: "Hello", type: :text)
frame.to_s # "\x81\x05\x48\x65\x6c\x6c\x6f"
