=======
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/)
and this project adheres to [Semantic Versioning](http://semver.org/).
# [unreleased]
## Added
- Add `WritablePduPacket` trait which is a common trait of all CFDP PDU implementations.
- Add `CfdpPdu` trait which exposes fields and attributes common to all CFDP PDUs.
- Add `GenericTlv` and `WritableTlv` trait as abstractions for the various TLV types.
## Fixed
- Set the direction field inside the PDU header field correctly explicitely for all CFDP PDU
packets.
## Changed
- Renamed `SerializablePusPacket` to `WritablePusPacket`.
- Renamed `WritablePduPacket.written_len` and `SerializablePusPacket.len_packed` to `len_written`.
- Introduce custom implementation of `PartialEq` for `CommonPduConfig` which only compares the
values for the source entity ID, destination entity ID and transaction sequence number field to
allow those fields to have different widths.
- Removed the `PusError::RawDataTooShort` variant which is already covered by
`PusError::ByteConversionError` variant.
- Ranamed `TlvLvError::ByteConversionError` to `TlvLvError::ByteConversion`.
- Renamed `PusError::IncorrectCrc` to `PusError::ChecksumFailure`.
## Removed
- `PusError::NoRawData` variant.
- `cfdp::LenInBytes` which was not used.
# [v0.7.0-beta.2] 2023-09-26
## Added
- `PacketId` trait impls: `Ord`, `PartialOrd` and `Hash`
- `SerializablePusPacket` trait: Add `to_vec` method with default implementation.
# [v0.7.0-beta.1] 2023-08-28
- Bump `zerocopy` dependency to v0.7.0
## Changed
- The `Tlv` and `Lv` API return `&[u8]` instead of `Option<&[u8]>`.
- `ByteConversionError` error variants `ToSliceTooSmall` and `FromSliceTooSmall` are struct
variants now. `SizeMissmatch` was removed appropriately.
- `UnsignedByteFieldError` error variants `ValueTooLargeForWidth` and `InvalidWidth` are struct
variants now.
- `TimestampError` error variant `InvalidTimeCode` is struct variant now.
## Added
- Added `raw_data` API for `Tlv` and `Lv` to retrieve the whole `Lv`/`Tlv` slice if the object
was created from a raw bytestream.
- Added `MsgToUserTlv` helper class which wraps a regular `Tlv` and adds some useful functionality.
- `UnsignedByteField` and `GenericUnsignedByteField` `new` methods are `const` now.
- `PduError` variants which contained a tuple variant with multiple fields were converted to a
struct variant.
# Added
- Added `pdu_datafield_len` getter function for `PduHeader`
## Removed
- `SizeMissmatch` because it is not required for the `ByteConversionError` error enumeration
anymore.
# [v0.7.0-beta.0] 2023-08-16
- 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.
- Converted `PusTm` class to more specialized `PusTmCreator` and `PusTmReader`
classes. The old `PusTm` class is deprecated now.
- Implement `Display` and `Error` for `StdTimestampError` properly.
- Remove some redundant `Error` suffixes for enum error variants.
- `CommonPduConfig`: `new_with_defaults` replaced by `new_with_byte_fields`.
## Added
- `source_data` and `app_data` API provided for PUS TM and PUS TC reader classes. These simply
call `user_data` but are also in line with the PUS packet standard names for those fields.
- Added new marker trait `IsPusTelemetry` implemented by `PusTmCreator` and `PusTmReader`.
- Added new marker trait `IsPusTelecommand` implemented by `PusTcCreator` and `PusTcReader`.
- `metadata_param` getter method for the `MetadataPdu` object.
- `Default` impl for CFDP `ChecksumType`
- `Default` impl for CFDP `CommonPduConfig`
## Fixed
- All `MetadataGenericParam` fields are now public.
- New setter method `set_source_and_dest_id` for `CommonPduConfig`.
# [v0.6.0] 2023-07-06
## Added
- Added new `util` module which contains the following (new) helper modules:
- `UnsignedEnum` trait as an abstraction for unsigned byte fields with variable lengths. It is
not tied to the ECSS PFC value like the `EcssEnumeration` trait. The method to retrieve
the size of the unsigned enumeration in bytes is now called `size`.
- `GenericUnsignedByteField<TYPE>` and helper typedefs `UnsignedU8`, `UnsignedU16`, `UnsignedU32`
and `UnsignedU64` as helper types implementing `UnsignedEnum`
- `UnsignedByteField` as a type-erased helper.
- Initial CFDP support: Added PDU packet implementation.
- Added `SerializablePusPacket` as a generic abstraction for PUS packets which are
writable.
- Added new `PusTmZeroCopyWriter` class which allows to set fields on a raw TM packet,
which might be more efficient that modification and re-writing a packet with the
`PusTm` object.
## Changed
- The `EcssEnumeration` now requires the `UnsignedEnum` trait and only adds the `pfc` method to it.
- Renamed `byte_width` usages to `size` (part of new `UnsignedEnum` trait)
- Moved `ecss::CRC_CCITT_FALSE` CRC constant to the root module. This CRC type is not just used by
the PUS standard, but by the CCSDS Telecommand standard and the CFDP standard as well.
# [v0.5.4] 2023-02-12
## Added
- `Clone` trait requirement for `time::cds::ProvidesDaysLen` trait.
- Added `Copy` and `Clone` derives for `DaysLen16Bits` and `DaysLen24Bits`.
# [v0.5.3] 2023-02-05
## Added
- `num_enum` dependency to avoid boilerplate code for primtive to enum conversions, for example
for the PUS subservices.
- `ecss.event` module containing a `Subservice` enum.
- `ecss.verification` module containing a `Subservice` enum.
- `ecss.scheduling` module containing a `Subservice` enum and some other helper enumerations.
- `ecss.hk` module containing a `Subservice` enum.
## Changed
- Added missing Service IDs to `ecss.PusServiceId` and marked in `#[non_exhaustive]`.
## Fixed
- `time.UnixTimestamp`: All constructors and `From` conversions now use the `new` constructor,
which should cause a correct conversion of 0 subsecond milliseconds to a `None` value.
# [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.
## Changed
- Renamed `PusTc` `raw` method to `raw_bytes` and add better docs to avoid confusion.
Deprecate `raw` to avoid breaking change.
- Added `raw_bytes` method to `PusTm`.
# [v0.5.1] 2023-01-22
## 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.
## Fixed
- `time::cds::TimeProvider`: Fixed a bug where subsecond milliseconds were not accounted for
when the provider has no submillisecond precision.
# [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.
