Struct Slot

pub struct Slot { /* private fields */ }

A connection slot wrapping the internal connection state.

Contains the four-tuple which maps to the slot, completing the loop for lookups (slotkey->4tuple,4tuple->slotkey). Usage of this acts similar to a slotmap where a dedicated SlotKey allows referring to a connection outside of its lifetime without introducing lifetime-tracked references and dependencies.

Internally used as the backing storage to open or accept a new connection.

Implementations

impl Slot

pub fn four_tuple(&self) -> FourTuple

Return the connection four tuple of the slot.

Note that the source or destination ports may be 0 if they have not been chosen yet. This happens when the connection has only been opened passively or no active SYN has been sent.
