Trait for UdpSocket

Required Associated Types§

source

type Time: Time

Time implementation used for this type

Required Methods§

source

fn connect<'async_trait>( addr: SocketAddr ) -> Pin<Box<dyn Future<Output = Result<Self>> + Send + 'async_trait>>
where Self: 'async_trait,

setups up a “client” udp connection that will only receive packets from the associated address

source

fn connect_with_bind<'async_trait>( addr: SocketAddr, bind_addr: SocketAddr ) -> Pin<Box<dyn Future<Output = Result<Self>> + Send + 'async_trait>>
where Self: 'async_trait,

same as connect, but binds to the specified local address for seding address

source

fn bind<'async_trait>( addr: SocketAddr ) -> Pin<Box<dyn Future<Output = Result<Self>> + Send + 'async_trait>>
where Self: 'async_trait,

a “server” UDP socket, that bind to the local listening address, and unbound remote address (can receive from anything)

source

fn poll_recv_from( &self, cx: &mut Context<'_>, buf: &mut [u8] ) -> Poll<Result<(usize, SocketAddr)>>

Poll once Receive data from the socket and returns the number of bytes read and the address from where the data came on success.

source

fn poll_send_to( &self, cx: &mut Context<'_>, buf: &[u8], target: SocketAddr ) -> Poll<Result<usize>>

Poll once to send data to the given address.

Provided Methods§

source

fn recv_from<'life0, 'life1, 'async_trait>( &'life0 self, buf: &'life1 mut [u8] ) -> Pin<Box<dyn Future<Output = Result<(usize, SocketAddr)>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Receive data from the socket and returns the number of bytes read and the address from where the data came on success.

source

fn send_to<'life0, 'life1, 'async_trait>( &'life0 self, buf: &'life1 [u8], target: SocketAddr ) -> Pin<Box<dyn Future<Output = Result<usize>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Send data to the given address.

Object Safety§
