pub enum ListenError {
    InvalidState,
    Unaddressable,
    InUse,
}

Error returned by TcpListener::listen

Requires the tcp-listener feature.

Variants

InvalidState

The listener is already listening on a different address, or bind_to_iface was called while it is open.

Unaddressable

The listen port is zero.

InUse

Another TCP listener is bound to the identical address.

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
