• Documentation fix.

• Bugfix release (see merge request [26][mr26] by @jeandudey for details).

• Added the trait CborLen and functions minicbor::len and minicbor::len_with to allow client code to calculate the length in bytes of a value's CBOR representation. See issue [32][i32] and merge request [23][mr23] for details.

• Fixes feature-handling, see pull request [48][pr48] by @dtolnay for details.

• Using #[cbor(transparent)] together with a custom codec (e.g. #[cbor(with = "...")]) will only override Encode::is_nil and Decode::nil if the has_nil attribute or its equivalent is present.

• Maintenance release, fixing an issue with blacklisting type parameter constraints, see commit 0f7cc0d8468b7cfbc8fb12833db6d6b47d54713d for details.

• Remove feature partial-derive-support. Encode and Decode can always be derived. See commits 21060b3272d4d09af88aa8543f682c8c4477a886 and 9038d3cced197588ae4d8d2c891d6f51029a9e7d for details.
• Rework encode::Write impls. The blanket impl for types implementing std::io::Write has been removed. The impl for Vec<u8> now always uses Infallible as its error type and minicbor::{to_vec, to_vec_with} no longer require feature "std". See commit 498043ddce69e3da0dcc66593afdeea0dd058fb8 for details.
• Depend on minicbor-derive-0.12.0.

• Remove cargo feature partial-skip-support. The method Decoder::skip is now always available. With cargo feature alloc, every CBOR item can be skipped over, otherwise attempting to skip over indefinite-length arrays or maps inside of regular arrays or maps will result in an error.
• Depend on minicbor-derive-0.11.0.

• Bugfix release (see pull request [26][pr26] by @carloskiki for details)

• Specialise Cow<_, [u8]> by adding implementations of minicbor::bytes::{EncodeBytes, DecodeBytes}.

• No change since 0.16.0-rc.1.

• Update documentation.

• Maintenance release (documentation tweaks).

• Maintenance release (documentation tweaks).

• ⚠️ Breaking ⚠️: The encoding of IP addresses changed (see commit fac39d5a). This affects the following types:

  • std::net::IpAddr
  • std::net::Ipv4Addr
  • std::net::Ipv6Addr
  • std::net::SocketAddr
  • std::net::SocketAddrV4
  • std::net::SocketAddrV6

  A new module minicbor::legacy is introduced which contains newtype wrappers for these types which continue to use the array-based encoding. Users can opt out of the new compact format by enabling the cargo feature "legacy" and importing the types from the legacy module.

• A new type minicbor::data::Int has been introduced (see merge request [20][mr20]) to allow encoding and decoding of the whole CBOR integer range [-2⁶⁴, 2⁶⁴ - 1].

• ⚠️ Breaking ⚠️: As a consequence of adding the new Int type, a new constructor minicbor::data::Type::Int has been added to denote those (signed) integers that do not fit into an i64. Similarly the new constructor minicbor::decode::Token::Int captures those values.

• ⚠️ Breaking ⚠️: encode::Error and decode::Error are now structs instead of enums. The actual error representation is hidden and errors are constructed with functions instead of creating enum values directly, for example Error::Message("foo") is now Error::message("foo"). This was done to support adding more information to error values, like the decoding position. For details see merge request [19][mr19].

• ⚠️ Breaking ⚠️: Removed the Clone impl of decode::Error.
• Added a new variant decode::Error::Custom (requires feature std) which contains an arbitrary Box<dyn std::error::Error + Send + Sync>.

• Extend the optionality of fields beyond Option. This applies to derived impls of Encode and Decode which make use of newly added methods Encode::is_nil and Decode::nil instead of Option::is_none and None. See issue [10][i10] and merge request [15][mr15] for details.

• Depends on minicbor-derive-0.7.0.

• Small bugfix release (see commit 68963dc for details).

• ⚠️ Breaking ⚠️: By default Decoder::skip is not available anymore. It can be enabled with feature flag "alloc" (implied by "std") or "partial-skip-support". The latter variant corresponds to the implementation of minicbor <= 0.9.1 but does not support skipping over indefinite-length arrays or maps inside of regular arrays or maps. The variant enabled by "alloc" supports skipping over arbitrary CBOR items. For more information see [feature flags][3] and issue [9][i9].

• Depends on minicbor-0.16.0-rc.1.
• A new attribute context_bound has been added to allow constraining the generic context type of the derived Encode or Decode trait impl with a set of trait bounds.

• ⚠️ Breaking ⚠️: The encoding of () and PhantomData has changed. See commit b6b1f907.
• ⚠️ Breaking ⚠️: The decode::Error::TypeMismatch constructor changed to use a data::Type instead of a u8 as its first parameter. See merge request [6][mr6] for details.
• Added feature flag alloc (implied by std), which enables most collections types in a no_std environment. See merge request [9][mr9] for details.
• Added ByteArray to support compact encoding of u8-arrays, similarly to the already existing ByteSlice and ByteVec types added in minicbor-0.6.0. See merge request [10][mr10] for details.
• Added Write impl for alloc::vec::Vec (see merge request [11][mr11] by @Hawk777).
• Depends on minicbor-derive-0.6.4.

• ⚠️ Breaking ⚠️: Change data::Type to distinguish between indefinite arrays, maps, bytes and strings, and regular ones by introducing constructors such as Type::ArrayIndef.
• Add new types decode::Token and decode::Tokenizer to allow decoding CBOR bytes generically as a mere sequence of tokens.
• Add a function display which displays CBOR bytes in [diagnostic notation][2].

• Bugfix: Type::read used 0xc9 instead of 0xc0 when reading Type::Tag.
• Add README.md

• Require minicbor-derive-0.6.1.

• Require minicbor-derive-0.6.0.

• Improve hygiene (see merge request [7][mr7]).

• Improve macro hygiene.

• Add README.md

• Maintenance release.

• Removes the &[u8] impl for Decode (see issue [4][i4]) and add a new module minicbor::bytes to support specialised encoding of CBOR bytes. This module provides the types ByteSlice and ByteVec which are substitutes for &[u8] and Vec<u8> respectively. See also the module documentation of minicbor::bytes.

• Require minicbor-derive-0.4.0.

• Adds Encoder::f16 to support encoding of f32 values as half floats. Complements the existing Decoder::f16 method and depends on the feature half.

• Added Encode and Decode impls for tuples (see merge request [1][mr1] by @koushiro).

minicbor-derive

• Added #[cbor(map)] and #[cbor(array)] attributes (see commit 40e8b240 for details).

minicbor-io

• Reader and AsyncReader always return UnexpectedEof when reading 0 bytes while decoding a frame, unless at the very beginning of a frame, when not even the length prefix has been read, where Ok(None) would be returned instead. Previous versions returned Ok(None) while reading a partial length prefix.

• Maintenance release (documentation tweaks).

• Fix link to documentation in Cargo.toml.

• Initial release which provides some I/O utilities.
