Trait EnqueueFd 

pub trait EnqueueFd {
    // Required method
    fn enqueue(&mut self, fd: &impl AsRawFd) -> Result<(), QueueFullError>;
}

An interface to enqueue a RawFd for later transmission to a different process.

This trait is intended to interact with Write as the mechanism for actually transmitting the enqueued RawFd. Specifically, the RawFd will be transmitted after a write() of at least 1 byte and, possibly, a flush().

Required Methods

fn enqueue(&mut self, fd: &impl AsRawFd) -> Result<(), QueueFullError>

Enqueue fd for later transmission to a different process.

The caller is responsible for keeping fd open until after the write() and flush() calls for actually transmitting the fd have been completed.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl EnqueueFd for fd_queue::mio::UnixStream

impl EnqueueFd for fd_queue::UnixStream

Enqueue a RawFd for later transmission across the UnixStream.

The RawFd will be transmitted on a later call to a method of Write. The number of RawFd that can be enqueued before being transmitted is bounded by FD_QUEUE_SIZE.
