}
Expand description

A trait for interacting with the pieces of packet metadata that are important for filtering.

Required Methods§

Source

fn take_connection_and_direction( &mut self, ) -> Option<(Connection<I, NatConfig<I, A>, BT>, ConnectionDirection)>

Removes the conntrack connection and packet direction, if they exist.

Source

fn replace_connection_and_direction( &mut self, conn: Connection<I, NatConfig<I, A>, BT>, direction: ConnectionDirection, ) -> Option<Connection<I, NatConfig<I, A>, BT>>

Puts a new conntrack connection and packet direction into the metadata struct, returning the previous connection value, if one existed.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
