tcp server callback

Required Associated Types

type T

data processed independently on a single connection, ensure data atomicity for a single connection

Required Methods

async fn conn<const CN: usize>( &self, endpoint: IpEndpoint, wch: &WriteChannel<'_, CN>, t: &mut Self::T, )

connection success call this

async fn dis_conn(&self, endpoint: IpEndpoint, t: &mut Self::T)

connection lost call this

async fn recv<const CN: usize>( &self, endpoint: IpEndpoint, buf: &[u8], wch: &WriteChannel<'_, CN>, t: &mut Self::T, )

recv tcp client data call this

async fn err(&self, err: SocketErr, t: &mut Self::T)

socket err will call this
only error notification will be made, no blocking and exit will be made
please do not use endless loops in this method

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
