- In readRequest, removed redundant assignment of c.firstBuf after the Read operation. The slice is already limited to n bytes read. - Changed resp from a value to a pointer in readRequest to avoid copying the struct when only a pointer is needed. - Added error handling in the Read method to return an error if readRequest fails, which was previously ignored. - Optimized the condition in Read to check for equality (c.bufStart == len(c.firstBuf)) instead of greater than or equal, as bufStart should never exceed len(c.firstBuf).
