The base execution context provided by the IP layer to transport layer protocols.

Required Associated Types

type DevicesWithAddrIter<'s>: Iterator<Item = Self::DeviceId>

The iterator given to BaseTransportIpContext::with_devices_with_assigned_addr.

Required Methods

fn with_devices_with_assigned_addr<O, F: FnOnce(Self::DevicesWithAddrIter<'_>) -> O>( &mut self, addr: SpecifiedAddr<I::Addr>, cb: F, ) -> O

Is this one of our local addresses, and is it in the assigned state?

Calls cb with an iterator over all the local interfaces for which addr is an associated address, and, for IPv6, for which it is in the “assigned” state.

fn get_default_hop_limits( &mut self, device: Option<&Self::DeviceId>, ) -> HopLimits

Get default hop limits.

If device is not None and exists, its hop limits will be returned. Otherwise the system defaults are returned.

fn get_original_destination( &mut self, tuple: &Tuple<I>, ) -> Option<(I::Addr, u16)>

Gets the original destination for the tracked connection indexed by tuple, which includes the source and destination addresses and transport-layer ports as well as the transport protocol number.

Object Safety

This trait is not object safe.
