Changelog

Unreleased

0.16.0 - 2023-02-28

Changes

Bug fix

0.15.1 - 2022-12-19

Small bug fix: Use fully qualified path when calling write as it may clash with other impls

0.15.0 - 2022-11-16

Breaking/Performance

  • Upgrade to bitvec 1.0.0 may cause some breaking changes in some code bases.
  • Performance note: Upgrade to bitvec 1.0.0 has shown negative performance impacts.

Changes

Bug fix

0.14.1 - 2022-10-09

Bug fix

  • Fix issue where endianness trickery wouldn't swap bytes correctly when reading less than the full amount into an integer (@caass) (#283)

Changed

0.14.0 - 2022-10-06

This release introduces a performance specialization/optimization in the read path for bytes

Breaking

  • Size enum removed in favor of BitSize and ByteSize, this change is to allow a performance optimization in the byte reading

0.12.0 - 2021-04-13

Breaking

  • const_generics feature enabled by default

  • DekuRead+DekuWrite implementations for Cow (@abungay) (#186)
  • DekuRead+DekuWrite implementations for HashMap (@abungay) (#199)
  • DekuRead+DekuWrite implementations for HashSet (@abungay) (#199)
  • DekuWrite implementations for &T (@abungay) (#199)
  • DekuRead+DekuWrite implementations for tuple (@abungay) (#198)

Other

0.11.0 - 2020-02-25

Breaking

  • Removed bitvec from deku::prelude (#181)
    • This will break custom reader and writer function definitions
    • bitvec is re-exported via: deku::bitvec:: (this contains bitvec::prelude::*)

Added

  • Added DekuEnumExt to provide extra utility functions to enums. (#176)
    • This trait is implemented on enums derived with #[derive(DekuRead)]
    • This trait currently contains 1 function: deku_id()
    • deku_id can be called on an enum variant to get the deku id of the variant
  • Added Incomplete(NeedSize) variant on DekuError (#177)
  • Added CODE_OF_CONDUCT.md
  • Code improvements (@wcampbell0x2a)

0.10.1 - 2020-02-25

0.10.0 - 2020-01-09

Breaking

  • Enum's which don't specify an id attribute now default to their discriminant value instead of being treated as a catch-all (#139)
  • Removed BitSize in favor of a new enum Size with two variants, Bits and Bytes (#138)
  • Added namespacing to internal variables. deku:: is used to access internal variables in token fields. (#150) For example, reader = "my_reader(deku::rest, deku::bit_offset)" or writer = "my_writer(deku::output)"
  • Introduced a lifetime to DekuRead in support of zero-copy reading (#158)

Added

  • Zero-copy reading on &[u8] (#158)
  • Padding related attributes: pad_bits_before, pad_bytes_before, pad_bits_after, pad_bytes_after (#163)
  • Assertion related attributes: assert, assert_eq (#164)
  • Ability to use more types in enum's type attribute (#162)
  • Ability to use LitByteStr in enum's id attribute, for example id = b"0x01" (#162)
  • Access to read offset via bit_offset and byte_offset internal variables. (#149) These are accessed via deku:: namespace, deku::bit_offset and deku::byte_offset. (#150)
  • #[deku(temp)] attribute, enabled via deku_derive proc-macro attribute. (#136) This allows reading/use of a field without it being stored in the container.
  • DekuRead+DekuWrite implementations for CString (#144)
  • DekuRead+DekuWrite implementations for NonZeroT types (#140)
  • DekuRead+DekuWrite implementations for bool (#161)
  • DekuRead+DekuWrite implementations for () (#159)
  • DekuRead+DekuWrite implementations for Box and Box<[T]> (#160)

Other

0.9.3 - 2020-12-14

[0.9.2 - yanked] - 2020-12-14

0.9.1 - 2020-10-31

  • Changed minimum bitvec version to 0.19.4 to have desired offset_from functionality (ferrilab/bitvec#86). This was missed in 0.9.0 release.
  • Code improvements (@wcampbell0x2a)

0.9.0 - 2020-10-30

  • Added magic attribute, this allows the ability to specify a set of bytes which must be present at the start of the data (@samuelsleight)
  • Added until attribute, this allows the ability to read until a given predicate (@samuelsleight)
  • Added bits_read and bytes_read container attributes, this allows the ability to specify an amount of bits/bytes to read inside a Vec (@samuelsleight)
  • Improved documentation
  • Refactored test cases
  • Code improvements (@wcampbell0x2a)

0.8.0 - 2020-09-29

  • write now takes a &mut BitVec instead of returning a BitVec, this optimization speeds up serialization (@agausmann)

The following items have been renamed: (@wcampbell0x2a)

  • Renamed id_type in favor of type
  • Renamed id_bits in favor of bits
  • Renamed id_bytes in favor of bytes

Internal:

  • Updated criterion to latest
  • Using tarpaulin for code coverage now
  • Swapped hex! macro (@inspier)
  • Code improvements (@wcampbell0x2a)

0.7.2 - 2020-09-02

  • Added ctx_default attribute, this allows the ability to specify defaults to types accepting a ctx if none are provided
  • Updated documentation regarding the concept of context and how it applies to some attributes
  • Added validation to id attribute
  • endian attribute now accepts an expression (still accepts big or little)
  • Updated bitvec dependency

0.7.1 - 2020-07-31

  • Added id attribute to top-level enums which allows to specify the enum id, for example a value coming via a context variable

0.7.0 - 2020-07-28

  • Added cond attribute which allows for conditional parsing or skipping of a field
  • Added id_pat attribute which allows pattern matching for enum variants

Community:

  • Added ctx attribute which adds the ability to pass context to child parsers from the parent (@constfold)
  • Internal refactoring of endian, bits and count attributes, they are now sugar around the ctx (@constfold)
  • Renamed to_bitvec to to_bits (@wcampbell0x2a)

0.6.1 - 2020-07-06

  • Enum variant specified without an id attribute is now considered the catch-all

[0.6.0] - 2020-06-22

  • Added DekuContainerRead and DekuContainerWrite to expose from_bytes, to_bytes and to_bitvec
  • Added release.toml
  • Added CHANGELOG.md to track changes
