Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[unreleased]

Added

• time::cds::TimeProvider
  • Add Ord and PartialOrd, use custom PartialEq impl to account for precision correctly.
  • Add precision_as_ns function which converts microsecond and picosecond precision values into nanoseconds.
  • Add conversion trait to convert cds::TimeProvider<DaysLen16Bits> into cds::TimeProvider<DaysLen24Bits> and vice-versa.
• time::UnixTimestamp
  • Add Ord and PartialOrd implementations.
  • Add Add<Duration> and AddAssign<Duration> implementations.

[v0.5.0] 2023-01-20

The timestamp of PusTm is now optional. See Added and Changed section for details.

Added

• PusTmSecondaryHeader: New new_simple_no_timestamp API to create secondary header without timestamp.
• PusTm: Add new_simple_no_timestamp method to create TM without timestamp
• New UnixTimestamp abstraction which contains the unix seconds as an i64 and an optional subsecond millisecond counter (u16)
• MS_PER_DAY constant.
• CUC: Added from_date_time and from_unix_stamp constructors for time provider.
• CUC: Add Add<Duration> and AddAssign<Duration> impl for time provider.

CDS time module

• Implement Add<Duration> and AddAssign<Duration> for time providers, which allows easily adding offsets to the providers.
• Implement TryFrom<DateTime<Utc>> for time providers.
• 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.
• New CdsTimestamp trait which encapsulates common fields for all CDS time providers.
• from_unix_secs_with_u24_days and from_unix_secs_with_u16_days which create the time provider from a UnixTimestamp reference.
• from_dt_with_u16_days, from_dt_with_u24_days and their ..._us_precision and ..._ps_precision variants which allow to create time providers from a chrono::DateTime<Utc>.
• 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.

[v0.4.2] 14.01.2023

Fixed

• CDS timestamp: Fixed another small logic error for stamp creation from the current time with picosecond precision. PR: #8

[v0.4.1] 14.01.2023

Fixed

• CDS timestamp: The conversion function from the current time were buggy when specifying picoseconds precision, which could lead to overflow multiplications and/or incorrect precision fields. PR: #7

[v0.4.0] 10.01.2023

Fixed

• Remove Default derive on CDS time provider. This can lead to uninitialized preamble fields.

Changed

• serde support is now optional and behind the serde feature.
• PusTcSecondaryHeaderT trait renamed to GenericPusTcSecondaryHeader.
• PusTmSecondaryHeaderT trait renamed to GenericPusTmSecondaryHeader.
• SpHeader: Former tc and tm methods now named tc_unseg and tm_unseg. Former new method now called new_from_single_fields.
• SpHeader: Renamed from_bytes to from_be_bytes. The function now returns the remaining slice as well.
• All CDS specific functionality was moved into the cds submodule of the time module. CdsShortTimeProvider was renamed to TimeProvider. PR: #3

Added

• SpHeader getter function sp_header added for PusTc PR: #6
• Added PFC enumerations: ecss::UnsignedPfc and ecss::RealPfc. PR: #5
• Added std::error::Error implementation for all error enumerations if the std feature is enabled.
• CUC timestamp implementation as specified in CCSDS 301.0-B-4 section 3.2. PR: https://egit.irs.uni-stuttgart.de/rust/spacepackets/pulls/4/files
• ACII timestamps as specified in CCSDS 301.0-B-4 section 3.5.
• Added MSRV in Cargo.toml with the rust-version field set to Rust 1.60.
• serde Serialize and Deserialize added to all types.
• Added const constructors for PacketId, PacketSeqCtrl and SpHeader.
• Added PartialEq and Eq derives to TimeProvider.
• SpHeader: Added serialization function into raw format write_to_be_bytes.
• Added 24-bit day field support for CDS short. The bit width is configured at type level via a generic parameter type passed to the cds::TimeProvider
• Added submillisecond precision support for cds::TimeProvider

[v0.3.1] 03.12.2022

• Small fix for faulty docs.rs build

[v0.3.0] 01.12.2022

Added

• EcssEnumerationExt trait which implements Debug, Copy, Clone, PartialEq and Eq in addition to EcssEnumeration

Changed

• EcssEnumeration trait: Rename write_to_bytes to write_to_be_bytes

[v0.2.0] 13.09.2022

Added

• Basic support for ECSS enumeration types for u8, u16, u32 and u64

Changed

• Better names for generic error enumerations: PacketError renamed to ByteConversionError
• CCSDS module: ssc abbreviations fully replaced by better name seq_count
• Time module: CcsdsTimeProvider::date_time now has Option<DateTime<Utc>> as a returnvalue instead of DateTime<Utc>
• PusTc and PusTm: new_from_raw_slice renamed to simpler from_bytes

[v0.1.0] 16.08.2022

Initial release with CCSDS Space Packet Primary Header implementation and basic PUS TC and TM implementations.
