Go Binary Protocols

Framing

• Length‑prefix
• Delimiter
• Out‑of‑band size

Varints

• 7 data bits + continuation bit
• Compact for small numbers
• Must handle malformed inputs

Incremental parsing

• Partial length
• Partial payload
• Return “need more” without consuming

Zero‑copy

• Slice into input buffer
• Copy only when you must retain

Safety

• Enforce max frame size
• Avoid overflow

Go tips

• Reuse buffers
• Keep allocs at 0 in parsers
