0.1.3

• Both readers and writers implement common core datatypes, including:
  • BOOLEAN, INTEGER, BITSTRING, OCTETSTRING, NULL, OBJECT IDENTIFIER,
  • SEQUENCE, SET, SET OF,
  • Explicitly/Implicitly tagged types.
• Public APIs of readers and writers are documented and most of them are tested. These seem almost frozen.
• Now it depends on “bit-vec” crate to handle bit strings.
• ASN.1 data models are now in asn1::models. These are waiting for refactoring and API change, as well as FromBer traits.

• Writing SET values and tagged values.
