According to MSDN [1], the `TCP_NODELAY` parameter should be of type `BOOL` which is 4 bytes. Due to a bug [2] in rustc passing a byte instead of an int, any program written in rust that tries to set that option on a socket will fail with a "Invalid parameter supplied" error. Turns out that setsockopt on linux does not want optlen to be less than 4 bytes [3]. Windows' behavior is the following: - For optlen <= 0, return SOCKET_ERROR and set last error to WSAEFAULT - For optlen > 0, ignore the optlen value and set the TCP_NODELAY value to one if the first byte of the given optvalue is not 0. This will fix any rust program using the hyper library to do HTTP requests.
