Enum nng::options::RecvFd

pub enum RecvFd {}

A raw file descriptor that can be used to poll for receiving on a socket.

This descriptor will be readable when a message is available for receiving on the socket. When no message is ready for receiving, it will not be readable.

While this may be useful for integrating into existing polling loops, the use of asynchronous I/O objects will be more efficient.

Applications should never attempt to read or write to the file descriptor.

Support

• All sockets.
