ccsds_spp

A no_std, heapless Rust implementation of the CCSDS Space Packet Protocol, suitable for embedded and real-time systems.

This library is intended for use in satellite software, space simulation, and telemetry/telecommand tooling. It is designed to be robust, portable, and usable in constrained environments. No allocator required.

---

Features

• no_std compatible
• Heapless: works in memory-constrained environments
• Bit-accurate parsing and encoding
• FromBits / IntoBits traits for masked operations
• CCSDS-compliant Version, PacketType, APID support
• Designed for integration into embedded systems or FFI-safe libraries

---

Example

use ccsds_space_packet::{PacketHeader, PacketType, Version, ApId};

let mut header = PacketHeader { data: [0u8; 6] };

header.set_version(Version::One);
header.set_packet_type(PacketType::Telemetry);
header.set_ap_id(ApId::from(42));

assert_eq!(header.get_version(), Version::One);
assert_eq!(header.get_packet_type(), PacketType::Telemetry);
assert_eq!(u16::from(header.get_ap_id()), 42);

Design Notes

This is a work in progress.

Focus is on correctness and portability over performance for now.

Library avoids panics where possible and returns Result<T, &str> for error handling.
