v0.1011.0

Breaking changes

• The (unstable) internal encoding traits & types continue to evolve.
  • Oneof traits now encode and decode slightly differently and the traits
    bearing an empty state now have special responsibility for guarding against
    value duplication and recording error locations.
  • Distinguished encoding traits now use a different context type,.
    RestrictedDecodeContext, which restricts the minimum tolerated canonicity
    and allows for early exits and detailed errors about the location of
    non-canonical data problems.
  • DecodeContext now has public method visibility.

New features

• Added support for core::time::Duration and std::time::SystemTime.
• Added 3rd party type support for the bstr crate and its BString type,
  which is a wrapper around Vec<u8> that acts like text but does not guarantee
  UTF-8 and does not require any validation.
• Added 3rd party type support for the chrono and time crates and most of
  their important types, available through new crate features.
• Oneof types can now be wrapped in Box (multiple times even, and either
  side of Option if you really want.)
• DistinguishedMessage: added "restricted" and "canonical" decoding methods
  alongside the existing "distinguished" ones, allowing decoding to stop early
  on canonicity errors.

Fixes

• Rectify an ambiguous usage of PartialEq that could potentially cause
  compilation failures when supported types in the program support cross-type
  equality.
• bilrost-derive: simplify some codegen to remove a needless let mut in
  derived decoding implementations.

Cleanups

• bilrost-types: parsing fractional seconds with more than 9 digits now
  simply truncates instead of erring.
• bilrost-types: parsing timestamps with "unknown local offset" timezones
  ("-00:00") is now tolerated, since the timezone information is discarded
  anyway.
• bilrost-types: improved fuzzing binaries for datetime parsing.
• New keywords and categories have been added to the crate metadata.
• Various small cleanups to the readme and to the code as rustfmt and clippy
  develop more and stronger opinions.
• Major reorganization of type implementations, especially of common value-trait
  implementations and third-party types. All that code is now filed under
  encoding::type_support and conditionally enabled at the file level. Impls
  for primitive and core types in the builtin encoders are still in those
  encoders' modules, but the value_traits module now contains only traits and
  macros and all conditionally-enabled code has been moved into type_support.
• A new fuzzer binary is available specifically for the newer types which have
  the newer, slightly more abstract encoding paths. These fuzzers are typically
  run in the order of hundreds to thousands of CPU hours per significant change,
  and are available for you to run as well.
