Extension methods for the standard TcpListener type in std::net.

Required Methods§

source

fn set_ttl(&self, ttl: u32) -> Result<()>

Sets the value for the IP_TTL option on this socket.

This is the same as TcpStreamExt::set_ttl.

source

fn ttl(&self) -> Result<u32>

Gets the value of the IP_TTL option for this socket.

For more information about this option, see TcpStreamExt::set_ttl.

source

fn set_only_v6(&self, only_v6: bool) -> Result<()>

Sets the value for the IPV6_V6ONLY option on this socket.

For more information about this option, see TcpStreamExt::set_only_v6.

source

fn only_v6(&self) -> Result<bool>

Gets the value of the IPV6_V6ONLY option for this socket.

For more information about this option, see TcpStreamExt::set_only_v6.

source

fn take_error(&self) -> Result<Option<Error>>

Get the value of the SO_ERROR option on this socket.

This will retrieve the stored error in the underlying socket, clearing the field in the process. This can be useful for checking errors between calls.
