This framework is in the early stages of development. Important features are missing. New releases
with breaking changes are released regularly, with all changes documented inside respective

UDP is already packet based which makes it an excellent fit for exchanging space packets.

space systems which do not have permanent contact like low-earth-orbit (LEO) satellites.
The most important task of a TC source is to deliver the telecommands to the correct recipients.
For modern component oriented software using message passing, this usually includes staged
demultiplexing components to determine where a command needs to be sent.
For component oriented software using message passing, this usually includes staged demultiplexing
components to determine where a command needs to be sent.
Using a generic concept of a TC source and a TM sink as part of the software design simplifies
the flexibility of the TMTC infrastructure: Newly added TM generators and TC receiver only have to
forward their generated or received packets to those handler objects.

# Modes
Modes are an extremely useful concept for complex system in general. They also allow simplified
system reasoning for both system operators and OBSW developers. They model the behaviour of a
component and also provide observability of a system. A few examples of how to model
different components of a space system with modes will be given.

@ -28,6 +28,12 @@ and this project adheres to [Semantic Versioning](http://semver.org/).
## Changed
- Renamed `ReceivesTcCore` to `PacketSenderRaw` to better show its primary purpose. It now contains
a `send_raw_tc` method which is not mutable anymore.
- Renamed `TmPacketSourceCore` to `TmPacketSource`.
- Renamed `EcssTmSenderCore` to `EcssTmSender`.
- Renamed `StoreAddr` to `PoolAddr`.
- Reanmed `StoreError` to `PoolError`.
- TCP server generics order. The error generics come last now.
- `encoding::ccsds::PacketIdValidator` renamed to `ValidatorU16Id`, which lives in the crate root.
It can be used for both CCSDS packet ID and CCSDS APID validation.
@ -76,6 +82,9 @@ and this project adheres to [Semantic Versioning](http://semver.org/).
## Removed
- Remove `objects` module.
- Removed CCSDS and PUS distributor modules. Their worth is questionable in an architecture
where routing traits are sufficient and the core logic to demultiplex and distribute packets
is simple enough to be application code.

//! CCSDS packet routing components.
//!
//! The routing components consist of two core components:
//! 1. [CcsdsDistributor] component which dispatches received packets to a user-provided handler
//! 2. [CcsdsPacketHandler] trait which should be implemented by the user-provided packet handler.
//!
//! The [CcsdsDistributor] implements the [ReceivesCcsdsTc] and [ReceivesTcCore] trait which allows to
//! pass raw or CCSDS packets to it. Upon receiving a packet, it performs the following steps:
//!
//! 1. It tries to identify the target Application Process Identifier (APID) based on the
//! respective CCSDS space packet header field. If that process fails, a [ByteConversionError] is
//! returned to the user
//! 2. If a valid APID is found and matches one of the APIDs provided by
//! [CcsdsPacketHandler::valid_apids], it will pass the packet to the user provided
//! [CcsdsPacketHandler::handle_known_apid] function. If no valid APID is found, the packet
//! will be passed to the [CcsdsPacketHandler::handle_unknown_apid] function.
//!
//! # Example

//! Telemetry and Telecommanding (TMTC) module. Contains packet routing components with special

//!
//! The distributor modules provided by this module use trait objects provided by the user to
//! directly dispatch received packets to packet listeners based on packet fields like the CCSDS
//! Application Process ID (APID) or the ECSS PUS service type. This allows for fast packet
//! routing without the overhead and complication of using message queues. However, it also requires

//! all received telecommands are sent to a special handler object called TC source. Using
//! a design like this makes it simpler to add new TC packet sources or new telemetry generators:

//! ECSS PUS packet routing components.
//!
//! The routing components consist of two core components:
//! 1. [PusDistributor] component which dispatches received packets to a user-provided handler.
//! 2. [PusServiceDistributor] trait which should be implemented by the user-provided PUS packet
//! handler.
//!
//! The [PusDistributor] implements the [ReceivesEcssPusTc], [ReceivesCcsdsTc] and the
//! [ReceivesTcCore] trait which allows to pass raw packets, CCSDS packets and PUS TC packets into
//! it. Upon receiving a packet, it performs the following steps:
//!
//! 1. It tries to extract the [SpHeader] and [spacepackets::ecss::tc::PusTcReader] objects from
//! the raw bytestream. If this process fails, a [PusDistribError::PusError] is returned to the
//! user.
//! 2. If it was possible to extract both components, the packet will be passed to the
//! [PusServiceDistributor::distribute_packet] method provided by the user.
//!
//! # Example
//!
//! ```rust
//! use spacepackets::ecss::WritablePusPacket;
//! use satrs::tmtc::pus_distrib::{PusDistributor, PusServiceDistributor};
//! use satrs::tmtc::{ReceivesTc, ReceivesTcCore};
//! use spacepackets::SpHeader;
//! use spacepackets::ecss::tc::{PusTcCreator, PusTcReader};
//!
//! struct ConcretePusHandler {
//! handler_call_count: u32
//! }
//!
//! // This is a very simple possible service provider. It increments an internal call count field,
//! // which is used to verify the handler was called
//! impl PusServiceDistributor for ConcretePusHandler {
//! type Error = ();
//! fn distribute_packet(&mut self, service: u8, header: &SpHeader, pus_tc: &PusTcReader) -> Result<(), Self::Error> {
//! assert_eq!(service, 17);
//! assert_eq!(pus_tc.len_packed(), 13);
//! self.handler_call_count += 1;
//! Ok(())
//! }
//! }
//!
//! let service_handler = ConcretePusHandler {
//! handler_call_count: 0
//! };
//! let mut pus_distributor = PusDistributor::new(service_handler);
//!
//! // Create and pass PUS ping telecommand with a valid APID
//! let sp_header = SpHeader::new_for_unseg_tc(0x002, 0x34, 0);
//! let mut pus_tc = PusTcCreator::new_simple(sp_header, 17, 1, &[], true);
//! let mut test_buf: [u8; 32] = [0; 32];
//! let mut size = pus_tc
//! .write_to_bytes(test_buf.as_mut_slice())
//! .expect("Error writing TC to buffer");
//! let tc_slice = &test_buf[0..size];
