Struct wasmtime_wasi::sync::TcpListener

source · [−]

pub struct TcpListener { /* private fields */ }

Expand description

A TCP socket server, listening for connections.

This corresponds to std::net::TcpListener.

This TcpListener has no bind method. To bind it to a socket address, first obtain a Pool permitting the address, and then call Pool::bind_tcp_listener.

Implementations

source

impl TcpListener

source

pub fn from_std(std: TcpListener) -> TcpListener

Constructs a new instance of Self from the given std::net::TcpListener.

This grants access the resources the std::net::TcpListener instance already has access to.

source

Returns the local socket address of this listener.

This corresponds to std::net::TcpListener::local_addr.

source

pub fn try_clone(&self) -> Result<TcpListener, Error>
