4.0.0

Attention This is a major release, with several API-breaking changes. See UPGRADING.md for instructions.

Thanks

• Jannik Schürg (oid, string verifications)

Added

• Add functions parse_ber_recursive and parse_der_recursive, allowing to specify maximum recursion depth when parsing
• The string types IA5String, NumericString, PrintableString and UTF8String do now only parse if the characters are valid.
• as_str() was added to BerObjectContent to obtain a &str for the types above. as_slice() works as before.
• Implement Error trait for BerError
• Add method to extract raw tag from header
  • BerObjectHeader now has a lifetime and a raw_tag field
  • BerObject now has a raw_tag field
  • Implement PartialEq manually for BerObject: raw_tag is compared only if both fields provide it
• Add type BerClass
• Start adding serialization support (experimental) using the serialize feature

Changed/Fixed

• Make header part of BerObject, remove duplicate fields
• Maximum recursion logic has changed. Instead of providing the current depth, the argument is now the maximum possible depth.
• Change the api around Oid to achieve zero-copy. The following changed:
  • The Oid struct now has a lifetime and uses Cow internally.
  • The procedural macro oid! was added.
  • Oid::from returns a Result now.
  • The Oid struct now encodes whether the oid is relative or not.
  • The Debug implementation now shows whether the oid is relative and uses the bigint feature if available.
  • The Oid::iter method now returns an Option. Oid::iter_bigint was added.
