Struct TcpServer 

pub struct TcpServer { /* private fields */ }

The TcpServer struct represents a TCP server with a listener and a notification mechanism.

Properties:

• listener: The listener property in the TcpServer struct is of type TcpListener. It is used to listen for incoming TCP connections on a specific port.
• notify: The notify property in the TcpServer struct is of type Arc<Notify>. Arc stands for “Atomically Reference Counted” and is a thread-safe reference-counting pointer. Notify is a synchronization primitive that allows threads to wait until a condition is satisfied

Implementations

impl TcpServer

pub async fn bind(addr: &str) -> Result<Self, Box<dyn Error>>

The function bind asynchronously binds a TCP listener to a specified address and returns a TcpServer instance wrapped in a Result.

Arguments:

• addr: The addr parameter in the bind function is a reference to a string that represents the address to which the TCP listener will bind. This address typically includes the IP address and port number on which the server will listen for incoming connections.

Returns:

The bind function returns a Result containing an instance of TcpServer if the operation is successful, or a boxed dyn Error trait object if an error occurs during the process.

pub async fn run(&self) -> Result<(), Box<dyn Error>>

The function run is an asynchronous Rust function that continuously accepts incoming connections, reads data from the socket, echoes it back, and can be shut down upon notification.

Returns:

The run function is returning a Result with an empty tuple () on success or a Box containing any type that implements the Error trait on failure.

pub async fn shutdown(&self)

The shutdown function in Rust asynchronously notifies one waiting task to shut down.
