Struct UdpSenderHelper 

pub struct UdpSenderHelper<Socket, MakeWritableFutFn, WritableFut> { /* private fields */ }

A helper for constructing UdpSenders from an underlying Socket type.

This struct implements UdpSender if MakeWritableFn produces a WritableFut.

Also serves as a trick, since WritableFut doesn’t need to be a named future, it can be an anonymous async block, as long as MakeWritableFn produces that anonymous async block type.

The UdpSenderHelper generic type parameters don’t need to named, as it will be used in its dyn-compatible form as a Pin<Box<dyn UdpSender>>.

Implementations

impl<Socket, MakeWritableFutFn, WriteableFut> UdpSenderHelper<Socket, MakeWritableFutFn, WriteableFut>

pub fn new(inner: Socket, make_fut: MakeWritableFutFn) -> Self

Create helper that implements UdpSender from a socket.

Additionally you need to provide what is essentially an async function that resolves once the socket is write-ready.
