Struct UnsupportedTcpOpts 

pub struct UnsupportedTcpOpts { /* private fields */ }

The caller set socket options this runtime cannot apply.

Carried inside an std::io::Error with ErrorKind::Unsupported by TcpOpts::reject_unsupported, and reachable again through io::Error::get_ref().downcast_ref().

Display names every offending option, not just the first: a caller who set two unappliable options and fixed the one the message mentioned would otherwise get a second, identical-looking failure.

Implementations

👎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
