Struct TcpListenerIter 

pub struct TcpListenerIter<'a, 'd> { /* private fields */ }

Iterator over the TCP listeners of a Stack, returned by Stack::tcp_listeners.

Each item borrows the stack, so only one can exist at a time. That is why this is not an Iterator and cannot be used in a for loop. Use while let:

let mut iter = stack.tcp_listeners();
while let Some((handle, item)) = iter.next() {
    let _ = (handle, item.is_open());
}

Implementations

impl<'d> TcpListenerIter<'_, 'd>

pub fn next(&mut self) -> Option<(TcpListenerHandle, TcpListener<'_, 'd>)>

Get the next TCP listener, with its handle.

Returns None when there are no more.
