Method UnsafePutVarInt64

go/fory/buffer.go:782–785

UnsafePutVarInt64 writes a zigzag-encoded varint64 at the given offset without advancing writerIndex. Caller must have called Reserve() to ensure capacity. Returns the number of bytes written (1-9).

(offset int, value int64)

// Caller must have called Reserve() to ensure capacity.
// Returns the number of bytes written (1-9).
func (b *ByteBuffer) UnsafePutVarInt64(offset int, value int64) int {
	u := uint64((value << 1) ^ (value >> 63))
	return b.UnsafePutVarUint64(offset, u)
}

// UnsafePutVarUint64 writes an unsigned VarUint64 at the given offset without advancing writerIndex.
// Caller must have called Reserve(16) to ensure capacity (for bulk writes).
