pub fn send(
fd: RawFd,
buf: Vec<u8>,
flags: Option<i32>,
) -> OperationProgress<Send> ⓘExpand description
Sends data on a connected socket.
§Returns
This function returns OperationProgress<Send>.
This function signature is equivalent to:
ⓘ
async fn send(RawFd, Vec<u8>, Option<i32>) -> BufResult<i32, Vec<u8>>§Behavior
As soon as this function is called, the operation is submitted into the io-driver used by the current platform (for example io-uring). If the user then chooses to drop OperationProgress before the Future is ready, the operation will NOT tried be cancelled, but instead “detached”.
See more what methods are available to the return type.
§Examples
async fn send_example() -> std::io::Result<()> {
let data = b"Hello, server!".to_vec();
let (bytes_sent, _buf) = lio::send(fd, data, None).await;
println!("Sent {} bytes", bytes_sent?);
Ok(())
}
