unreleased

v0.17.0 2025-11-06

Changed

  • CdsCommon renamed to CdsBase
  • cfdp: Removed FileDirectiveType variant *Pdu suffix
  • ecss: Renamed Subservice to MessageSubtypeId
  • Simplified CDS short timestamp, contains one less field which reduced serialization length.
  • Renamed UnsignedEnum::value to UnsignedEnum::value_raw, value is reserved for the const value getter.
  • Renamed CcsdsPrimaryHeader::from_composite_fields to CcsdsPrimaryHeader::new_from_composite_fields
  • Renamed PusPacket::service to PusPacket::service_type_id and PusPacket::subservice to PusPacket::message_subtype_id. Also added PusPacket::message_type_id. Performed the same change for the ECSS PUS C secondary header traits.

Added

  • Added CcsdsPacketCreator, CcsdsPacketReader, CcsdsPacketCreatorWithReservedData and CcsdsPacketCreatorOwned which simplify the process of creating full CCSDS space packets.
  • Added new optional portable-atomic because portable atomics might not work on every architecture in addition to requiring atomic CAS support enabled inside for the crate.

Fixed

  • All core::sync::Atomic? usages are feature gated properly to allow compilation on systems without atomic CAS.

v0.16.1 2025-09-26

Fixed

SpHeader::packet_len is public now.

v0.16.0 2025-09-24

  • Bump Rust MSRV to v1.83

Changed

  • PusTcCreator has its own service, subservice and apid methods and does not require trait imports anymore.
  • CFDP NAK PDU SegmentRequestIter is not generic over the file size anymore. Instead, the iterator returns pairs of u64 for both large and normal file size.
  • PusVersion::VersionNotSupported contains raw version number instead of PusVersion enum now to make it more flexible.
  • pus_version API now returns a Result<PusVersion, u8> instead of a PusVersion to allow modelling invalid version numbers properly.
  • Renamed CcsdsPacket::total_len to CcsdsPacket::packet_len
  • Renamed SequenceCountProvider to SequenceCounter
  • Renamed SeqCountProviderSimple to SequenceCounterSimple
  • Renamed CcsdsSimpleSeqCountProvider to SequenceCounterCcsdsSimple
  • Renamed SeqCountProviderSync to SequenceCounterSync
  • Renamed PusPacket::opt_crc16 to PusPacket::checksum
  • Renamed PacketSequenceCtrl to PacketSequenceControl
  • ECSS checksum generation is now optional as specified in the standard. Added has_checksum parameters for ECSS TM/TC creators and readers to reflect this.

  • SpHeader::packet_len direct method.
  • AckFlags which is implemented with bitbybit::bitfield
  • ApidOutOfRangeError and SequenceCountOutOfRangeError
  • Added PUS A legacy support for telecommands inside the ecss.tc_pus_a module

[v0.11.0-rc.1] 2024-04-03

Major API changes for the time API. If you are using the time API, it is strongly recommended to check all the API changes in the Changed chapter.

Fixed

  • CUC timestamp was fixed to include leap second corrections because it is based on the TAI time reference. The default CUC time object do not implement CcsdsTimeProvider anymore because the trait methods require cached leap second information.

  • UnixTime now has a nanosecond subsecond precision. The new constructor now expects nanoseconds as the second argument.
  • Added new UnixTime::new_subsec_millis and UnixTime::new_subsec_millis_checked API to still allow creating a timestamp with only millisecond subsecond resolution.
  • CcsdsTimeProvider now has a new subsec_nanos method in addition to a default implementation for the subsec_millis method.
  • CcsdsTimeProvider::date_time renamed to CcsdsTimeProvider::chrono_date_time.
  • Added UnixTime::MIN, UnixTime::MAX and UnixTime::EPOCH.
  • Added UnixTime::timelib_date_time.
  • Error handling for ECSS and time module is more granular now, with a new DateBeforeCcsdsEpochError error and a DateBeforeCcsdsEpoch enum variant for both CdsError and CucError.
  • PusTmCreator now has two lifetimes: One for the raw source data buffer and one for the raw timestamp.
  • Time API from_now* API renamed to now*.

Removed

  • Legacy PusTm and PusTc objects.

  • Moved MSRV from v1.60 to v1.61.

Changed

  • PusPacket trait: user_data now returns &[u8] instead of Option<&[u8]>. Empty user data can simply be an empty slice.
  • Moved ECSS TC components from tc to ecss.tc.
  • Moved ECSS TM components from tm to ecss.tm.
  • Converted PusTc class to more specialized PusTcCreator and PusTcReader classes. The old PusTc class is deprecated now.

[v0.5.2] 2023-01-26

Added

  • Added .gitignore.

Fixed

  • Correct implementation of Trait PartialEq for PusTc and PusTm. The previous auto-derivation were incorrect because they also compared fields unrelated to the raw byte representation.

  • get_dyn_time_provider_from_bytes: Requires alloc support and returns the correct TimeProvider instance wrapped as a boxed trait object Box<DynCdsTimeProvider> by checking the length of days field.
  • Added constructor function to create the time provider from chrono::DateTime<Utc> and a generic UNIX timestamp (i64 seconds and subsecond milliseconds).
  • MAX_DAYS_24_BITS which contains maximum value which can be supplied to the days field of a CDS time provider with 24 bits days field width.

  • Add from_bytes_with_u24_days and from_bytes_with_u16_days associated methods

Changed

  • (breaking) unix_epoch_to_ccsds_epoch: Expect and return i64 instead of u64 now.
  • (breaking) ccsds_epoch_to_unix_epoch: Expect and return i64 instead of u64 now.
  • (breaking) PusTmSecondaryHeader: Timestamp is optional now, which translates to a timestamp of size 0.
  • (breaking): PusTm: Renamed time_stamp method to timestamp, also returns Optional<&'src_data [u8]> now.
  • (breaking): PusTmSecondaryHeader: Renamed time_stamp field to timestamp for consistency.
  • (breaking): Renamed from_now_with_u24_days_and_us_prec to from_now_with_u24_days_us_precision. Also did the same for the u16 variant.
  • (breaking): Renamed from_now_with_u24_days_and_ps_prec to from_now_with_u24_days_ps_precision. Also did the same for the u16 variant.
  • CcsdsTimeProvider trait (breaking):
    • Add new unix_stamp method returning the new UnixTimeStamp struct.
    • Add new subsecond_millis method returning counter Option<u16>.
    • Default impl for unix_stamp which re-uses subsecond_millis and existing unix_seconds method.
  • TimestampError (breaking): Add DateBeforeCcsdsEpoch error type because new CDS API allow supplying invalid date times before CCSDS epoch. Make TimestampError with #[non_exhaustive] attribute to prevent future breakages if new error variants are added.
