encodeHeaderInto

encodeHeaderInto(buffer, header): void

Defined in: packages/protocol/src/wire-format.ts:165

Encode a frame header INTO an existing buffer (zero allocation).

Use this with a pre-allocated buffer to avoid allocation overhead in high-throughput scenarios (e.g., ring buffer pattern).

Parameters

buffer

Buffer

Target buffer (must be at least HEADER_SIZE bytes)

header

FrameHeader

Header to encode

Returns

void

Example

const headerBuf = Buffer.allocUnsafe(HEADER_SIZE);
encodeHeaderInto(headerBuf, {
  methodId: 1,
  flags: 0,
  requestId: 42,
  payloadLength: 1024,
});
socket.write(headerBuf);
